Thanks Peter for taking your valuable time and sharing it with others. I worked for NASA running the MOTS (MiniTrack Optical Tracking System) at Orroral Valley in Australia. Out spacecraft shots were captured on Kodak F103 10" x 8" Glass plates, Our camera/systems cost would bankrupt small Nations. I mainly use Nikon today, Hasselblad and Linholf rail systems, .. display only now. Time to down-load Sequator.... Thanks again Peter.
Very good video. FYI Pete mentioned using more than 10 pictures not being worth it. I happily disagree with Pete and followed what the deep sky guys do. This weekend I took and stacked 8 minutes worth of 6 second photos with my Nikon D3200 with a 35mm at f1.8 ISO400 and had INCREDIBLE results! I wish I could share a picture here. I turned on most of the settings - Auto Brightness, High Dynamic Range, Remove Dynamic Noise, Reduce Light Pollution. Very little post editing needed. The 24mm @f2.8 ISO400 and 18-70mm @ f3.5 ISO 400 also looked pretty good but not as much detail. I am trying to stitch together a a 6 picture pano of the 35mm to get more sky but am having trouble with differences in the color of the sky from picture to picture.
I've been looking for a Windows program that will do what Starry Landscape Stacker (Mac only) does, and this is probably better. You did a great job on the tutorial - it really helped me get started. I do have a few suggested workflow changes and a few comments: * you can do this in Photoshop using layers, smart objects, and the mean or median blend mode. It takes a lot more time that this does, but it is possible (I have not had issues with align layers working) * I'd suggest doing a dark frame at the start and end of the sequence, as the hot pixels are related to the heat developed in the sensor * LR and ACR do have lens profiles for the Rokinon 14mm f/2.8, which is what I assume you're using - you have to manually select the lens (manufacturer, model) and do this on the RAW file (not a TIFF) * I found that Sequator's results were much better when I did (almost) all the edits in post. I apply lens corrections only in LR and export the files as DNGs. The Rokinon 14mm is a fantastic lens for the money, but it does have a lot of barrel distortion. * the light pollution filtering works really well. I had the best results with uneven/100% strength/intelligently-aggressive set * Sequator does a good job of noise reduction (far better than reducing the noise in a single image) but the output files still need some noise reduction (I used Nik Dfine2). The light pollution removal (I think) also added a purplish line on the horizon which was easily removed with a manual chromatic aberration adjustment in LR. * rather than setting all the options from scratch each time, save the project. For a new set, open the project (.sep file), replace the base frame and star images, and re-mask the sky Thanks again for putting this together.
i was looking around for rookie friendly AP programs and i found your channel , and since i am a rookie and you explained this so well that i even understood , i subscribed ,thanks a bunch
Subscribed to your channel! I have been binging on the content! I have a few good shots of the Milky Way w/o using a tracker, and now that I have a tracker I am ready to take the next exciting steps :) Keep up the great work
I am just starting in astrophotography and need to know if you are using Sequator as a Photoshop plug-in? I have had my Ioptron Star Track Pro for a few years and just now am getting around to using it because your tutorials are great and easy to understand.
I van recommend to use Sequator with different light Pollution filters and autobrighyness on/of, getting different results and put them afterwards together with a HDR program to get more output from dark regions - especially from a dark foreground. A mice feature in Sequator is the time lapses function to put let's say 5 images together and go through all images. So it is possible to get more dynamic in your time lapse.
Awesome vid. Just bought a Samyang 16mm f/2.0 for shooting the milky way. This tutorial is excellent and this software seems way less overwhelming than photoshop. Thanks, bro!
Thanks for your great video. Sequator worked perfectly well to render my milky way shoot at 14mm while Photoshop failed completely. I really appreciate your tutorials. Cheers.
I am so confused about one thing when using Sequator. I take my star photos in RAW, open them in "PhotoDirector 10" do exactly what you suggest, then export the files to a folder as TIFF. I then proceed to open Sequator, and add the TIFF star images. I then get a message in the main screen "read failed! Unsupported format or invalid path. But at the sametime in the work box to the left, I can see all my TIFF files under Star Images with a green light. And the middle Base image purple. Now if I do the exact same thing, but using RAW to import it works! I am told that it is better to use TIFF than RAW. I didn't even think Sequator would read RAW?
I see a light source in your pic and yet still the milky way is clear before even to stack. What dose it take to have clear milky way with a light pollution.
Any idea why the Sequator screen goes black when I try to paint the sky to freeze the ground? I'm using ON1 Raw 2020 to export my images to Tiff. I'm using the latest version but also got the same results with an older version.
great tutorial I was looking for tutorial in how to do stacking with GIMP. I am very glad I found your tutorial. Can't wait to go home and play, thanks.
In a nutshell -- is there a huge difference in results between using a stacking program vs shooting long exposures with a tracker. Thanks for these great videos -- I'll keep watching.
I would say there is a noticeable difference. Stacking short exposures is a good first step, but a star tracker will take things to a new level. You'll be able to pull out a lot more fine detail and color once you start shooting 2+ minute exposures. You could even stack multiple longer exposures together, but usually a single image is good enough. The only real downside of using a star tracker, and taking longer exposures, is hot pixels. They tend to blend in with the stars, but I still find them to be a pain. There are ways to fix them, but I'm still trying a few different techniques to determine the best option
@@PeterZelinka Thanks for that -- The prospect of taking really good night sky shots has opened up new possibilities for me. When I am ready to get out there, I will definitely be taking your online course. Thanks again.
I will try having the camera and telephoto closer to the centre of the Star Adventurer as well as move the counter weight closer to the mount on the counterweight shaft. Tightening the clutch after polar alignment with Polemaster may solve the balance problem with long telephotos still within the weight limits of the mount.
thanks for letting me know about this program. It‘s pretty good. I tried it. I needed an alternative because I recently encountered problems with deep sky stacker where it wouldn‘t stack all of my light frames, only half of them. They where shot at different nights and I tried many times with different file group tabs an so on,but nothing worked. And sequator seems to stack eyerthing, no problem at all.
Peter...Thank you for all the amazing and informative videos. I am just getting started with shooting the night sky and have been taking a ton of notes from a lot of your videos. For now I am just going to be doing milky way with the rokinon 14 mm f2.8 on my Nikon d5600 and also using the skyguider pro you recommended in one of your videos. I had a question when it comes to stacking, besides the "lights" and "darks" which i think you mentioned can be done anywhere and anytime, when it comes to actually taking the pics of the foreground I assume the 2-4 minute exposure is with the skyguider not rotating...and then after that shot turn on the rotation for the milky way? When it comes to taking the pics of the milky way, once you find the right shutter speed (between 2-4 minutes) do you take lots of pics at that sweet spot and then stack them, or do you vary the time from pic to pic and then stack them? Lastly, with the camera on the skyguider is it possible to reduce the iso down to 400, or for night sky shots is it always best to shoot at iso 800 and above? Sorry for all the questions, Im just trying to make sure I am covering the main topics as I am planning on going to Cheery Springs State Park either Wed Aug 28th or 29th to shoot the milky way.
Great video man! Regarding techniques to map your lens's vignetting....is there a difference in quality between the 2 methods you mentioned (Lightroom/Photoshop post-processing vs. photography a bright white frame)? The reason I ask, is that I have seen slight compromises in corner sharpness (i.e. the parts that were vignetted) when using the Lightroom method. Was just wondering if it would be worth the extra time and effort to do it the other way instead. Thanks!
Do you need anything to install, I tried they wanted me down Microsoft program but my computer said I couldn’t do it because I have a later version, can you get override this or will the new version work
Hi, Peter - thank You for a good tutorial. One question for the Orion nebula - which lens/ focal length did you use for those photos? Thank`s in advance. Stein
I've been bouncing between Sequator and DSS, and always seem to be drawn back to Sequator. DSS does allow use of dark bias frames, but frankly, at my current skill level, I haven't noticed any improvement. Sequator is sooo unknown/underrated. Do the creator a favor and buy him a 'cup of coffee' (Paypal link on his website sites.google.com/site/sequatorglobal/encourage).
I personally edit all of my RAW files, including the dark frames, and save them as TIFFs first. Then I drop those into sequator. The dark frames should have the same edits applied as the normal photos. Editing the RAW files first helps to reduce the color noise and vignette, among other things. I know many other people would argue that you should only use RAW photos and not do any editing before stacking, but I disagree.
Good question! I actually don't have many stacked images with trees in them, but I did find one example to test. It worked surprisingly well. There were a few artifacts around the trees, which looked like black star trails. Besides those minor streaks of black, everything else looked really good! If you have a really complicated scene with trees, I think Sequator would have some problems. However, I do have a post-processing tutorial for blending complicated scenes like that in Photoshop. You can watch that video here: ua-cam.com/video/x2dVRoyyFrc/v-deo.html
For wide field nightscape, do you prefer to stack or bring the tracker for 1 long exposure instead. Does this make the tracker less useful and more for just deepsky photos. Which has better quality?
I normally prefer using a star tracker. There are a few drawbacks though. Since I normally take a 4 minute exposure, I have a ton of hot pixels. Therefore, I used Long Exposure Noise Reduction, which effectively increases the total exposure time to 8 minutes. That's a long time to spend on a single photo. I've gotten much better images overall when using a star tracker. Photo stacking isa good way to reduce grain, but it has its limits.
I try to use it with the latest 4.x WINE on Apple and it seems so fast and promising....BUT CRASHES AT THE END OF PROCESSING THE LAST IMAGE. Wish there was a Mac addict who would make a WINE bottle of this...
Hi Peter,thanks for the test.i did some test too. there are two problems. 1:the stacked image is always darker than the originals.short of dark side and white side according to histagram. 2:if there is a bright thing moving on foreground e.g. a car,we we will see a black stripe on stacked image,in that case we still need photoshop to mask it. did you test Registar? TKS
When i go to download the Microsoft Visual C++ it says my computer already has another version thats installed. So i tried to download the program and it wont run it? Any ideas...
Do you use Sequator to merge a long exposure foreground shot with ,say, 10 sky shots? Or do you just process stack the star shots in Sequator and then combine them with the foreground shot in LR or PS? Thanks
Sequator Down Sizes my files? - I have been using a Nikon D850 (8200 x 5500 pixels) for some astrophotography. Why is it when I run the images thru Sequator the output file is about 4144 x 2760? Am I missing something? I would like to keep the pixels if possible . Any ideas? The software work very well and is fast. By the way you have a great channel!
@@PeterZelinkaGot it figured out, my fault. I was using the 'merge 4 pixels' option. Therefore reducing the output file size. You have a good channel, keep up the good work. Thanks.
Hey Peter, a qns pls: I notice random blotches of green in the background of the sky, which also appeared in all my milk way photos. any idea what is that and how to get rid of it?
just used my first star tracker tonight, 10 x 4min exposures of the night sky. Should I edit each individually to bring out all the detail then stack or should i stack then bring out all the detail?
It really depends on your camera. Most people online recommend stacking your RAW photos, then taking that stacked image into Photoshop. This is a good idea if you also have dark frames and flat frames. However, I do things differently. I normally edit my RAW photos first. I want to fix the overall Exposure, White Balance, apply lens profile corrections, and any other small adjustments. Then I sync those changes with all of the photos. I save them as 16bit Tiff files next. Finally, I use Sequator to stack those Tiff files. I'd recommend trying both approaches and see what works better for you.
Hi, thank you for the tut! I tried Sequator in the past and never felt happy with the results, so I gave it another try now and its the same experience. It does not seem to matter which selection of settings I choose I end up with a much duller and lower exposed looking image compare to view one of the images making up up the stack in camera raw. Am I missing or doing something wrong or is that the way its suppose to be?
@@PeterZelinka Wide Angle. Since my post I am discovered that the follow works best for me. The images I important should be Tiff and not DGN. I also than have Auto Brightness and HDR set to On and my colourspace set to Linear. This yields the best results for me.
Can someone tell me the BEST astrophotography lens that can mount a Canon like Canon T8i or Canon 90D? I heard of IRIX 15mm f/2.4 as well as Rokinon? Any suggestion of the BEST lens that is amazing in all aspects that can take nice shots of the Milky Way as well as Orion Nebula?
CelebrityLyrics I have no particular experience yet bu I'd say that a fast lense 2.8 and below are just nice! Rokinon is well known in this area because of their performance/price ratio. But Nikon, Canon, Tamron, Sigma lenses are all fine!
Dazza dizzy For the light frames, put a t-shirt on top of your lens and apply a light source like your smartphone or tablet on top. Take 10-15 shots with same ISO setting and speed as your sky pictures. This will reduce/eliminate the vignetting on your final photo.
I am having problems with sequator, I went through and used the software exactly how he states in the video and my final images look all crazy or come out with the foreground out of focus. Maybe this is an effect of stacking because all of the images I am using are in focus. Also the images I am using have a lot of light pollution which I cannot escape because of where I live. Does anyone have any suggestions?
I'm having a problem installing this program. I'm running windows 10 with an i5 processor. when I go to install the 2015 C++ the an error pops up and says something along the lines of there is already another version and it can not continue with the installation and to go to the control panel to configure or remove it. LOL there are like five or six different versions in there and I don't have a clue which one to remove or configure . I really want to give this program a go but I can 't find anything to point me in the right direction to get there.
did you try installing Sequator yet? Or are you still stuck on the C++ installation? You could always remove those other C++ runtimes, but that might screw up another program you have installed.
Peter Zelinka I had to uninstall the 2017 version C++ before I installed the 2015 version. I may have to go back and reinstall the 2017 C++. But so far, nothing seems to be effected by the 2017 one not being there any more. If something does comes up, I'll know what to check forst.
If it took FITS files, Sequator would be even better. I use Sequator for my Milky Way shots taken with my Nikon, but my DSO shots (sometimes numbering in the 100’s for each target) captured with my dedicated Astro camera are FITS files. Anybody know a way to batch convert numerous FITS files to TIF files?
2 years old but if you or anyone else sees this, it's a similar process where instead of taking many exposures and stacking them, you actually record a video and use a program to stack all those hundreds/thousands of frames, AutoStakkert
I just tried it out, it seems to work very well, but I can't find the result file anywhere... I tried several times changing the output folder, but I never find the result file in any attempt... :( do you know anything about this problem??
You specify where the output is saved to, so it should be right where you left it. Try going through the process again, and double clicking the Output button, then navigate to your desktop. After it's finished processing, you should see the TIF file there. If not, I'm not sure what could be going wrong
unluckly I did several times and I can't find the file neither a folder, if created in the program. I can see the file and the folder in sequator, but I can't open them. If I click on the "open" botton on top of the preview it says I need to log in in my Adobe account, I click on log in now, but it doesn't do anything. I'm already in my account in photoshop and adobe creative cloud, but it still doesn't work... that's a bummer, the stacking seemed pretty great!
@@danielefr- Change your default TIF file viewer so something other than Photoshop or Lightroom, that's why your are getting the adobe bs. If you are Windows based try the Microsoft Image viewer or IrFanView.
'DSS always stops, running out of memory' - really? Mine never has even processing 500+ 16mb subs with darks, flats, and dark flats. Takes maybe 5 minutes. Maybe your machine needs more memory?
Hey Peter, Could I get your thoughts please? I have just stacked 6 images and clicked open and it just seems to run forever, should it open directly in PS? I can see the stacked file in the folder but from within Sequator it doesn't open....CHeers Grahame
Hmmm, that's odd. I'm really not sure why it wouldn't open the TIFF into Photoshop. There's a ton of variables that might be causing that. If I had to guess, here are a few: Default program set to open TIFF files, random software bug, Photoshop version incompatibility, etc... I would simply navigate to the folder where you saved the TIFF file and either right click to 'Open With - Photoshop' or open the TIFF once you've started Photoshop. Either way should work fine and allow you to continue with the workflow
Just downloaded it and used it. Absolutely brilliant program, especially for wide field lens shots. Many thanks.

Therefore, I used Long Exposure Noise Reduction, which effectively increases the total exposure time to 8 minutes. That's a long time to spend on a single photo.
I've gotten much better images overall when using a star tracker. Photo stacking isa good way to reduce grain, but it has its limits.
thanks so much, can't wait to give this program a try
Is it tiff or tif? Coz i just converted my RAF files to Tiff and now i get an error message "read failed. unsupported format or invalid path"
Tiff and Tif are the same thing. It sounds like the files may have gotten corrupted or something. I'd try redoing the process
Hi, great tutorial. One question, can this programme be used for other photo stacking subjects such as macro, or is it just for astrophotography.
The algorithms are designed for astrophotography specifically. I would recommend using Photoshop to stack macro images
@@PeterZelinka ok thanks.
Awesome information Peter!!! What focal length did you use for Orion photos?
I believe I was at 600mm
So all you do to stack is take more than one picture? Or do those pictures have to be different exposures?
ARE YOU SERIOUSS your base image is my own life goal on Milky Way lol
Where did you shoot that? Altitude, distance from abitations etc etc
I try to use it with the latest 4.x WINE on Apple and it seems so fast and promising....BUT CRASHES AT THE END OF PROCESSING THE LAST IMAGE.
Wish there was a Mac addict who would make a WINE bottle of this...
Looks worth a try. Thanks for the great tutorial on it. What lens did you use for the Deep Space Orion photos?
I normally use the Tamron 150-600mm lens for my astro shots
whats the MAC alternative?
StarryLandscapeStacker
Comet stacking possible ?
Hi Peter,thanks for the test.i did some test too.
there are two problems.
1:the stacked image is always darker than the originals.short of dark side and white side according to histagram.
2:if there is a bright thing moving on foreground e.g. a car,we we will see a black stripe on stacked image,in that case we still need photoshop to mask it.
did you test Registar?
TKS
There is an option in there to remove things like airplane trails but I have not tried it.
When i go to download the Microsoft Visual C++ it says my computer already has another version thats installed. So i tried to download the program and it wont run it? Any ideas...
Hey Peter! For whatever reason I'm getting error on sequator when stacking "Reducing Noise Failed". Any idea what might be causing that?
I'm not sure, that's the first I've heard of that error. I don't see it mentioned on his website either
Do you use Sequator to merge a long exposure foreground shot with ,say, 10 sky shots? Or do you just process stack the star shots in Sequator and then combine them with the foreground shot in LR or PS? Thanks
Yeah, I do the blending in Photoshop usually. I only use Sequator to stack and align deep space shots or short exposures at wide angles
Hi, can I use Sequator to export/import to On1 2020?
Beautiful and helpful tutorial. Thank you
Can Sequator handle FITS files?
Hi, I can't get it to download and open zip file
Sequator Down Sizes my files? - I have been using a Nikon D850 (8200 x 5500 pixels) for some astrophotography. Why is it when I run the images thru Sequator the output file is about 4144 x 2760? Am I missing something? I would like to keep the pixels if possible . Any ideas? The software work very well and is fast. By the way you have a great channel!
Hmm, that's odd. I haven't noticed that before. Are you running the RAW files through?
@@PeterZelinkaGot it figured out, my fault. I was using the 'merge 4 pixels' option. Therefore reducing the output file size. You have a good channel, keep up the good work. Thanks.
What stacking solutions are available for Mac?
The two main options are Starry Sky Stacker for deep space images, and Starry Landscape Stacker for wide angle photos.
Hey Peter, a qns pls: I notice random blotches of green in the background of the sky, which also appeared in all my milk way photos. any idea what is that and how to get rid of it?
Airglow? Maybe?
I watched this video and immediately decided to download and try it. Unfortunately, it's a Windows-only application. sigh... back to DSS. ugh.
appears to work when running under LINUX MINT 19.3 with WINE.
just used my first star tracker tonight, 10 x 4min exposures of the night sky. Should I edit each individually to bring out all the detail then stack or should i stack then bring out all the detail?
It really depends on your camera. Most people online recommend stacking your RAW photos, then taking that stacked image into Photoshop. This is a good idea if you also have dark frames and flat frames.
However, I do things differently. I normally edit my RAW photos first. I want to fix the overall Exposure, White Balance, apply lens profile corrections, and any other small adjustments. Then I sync those changes with all of the photos. I save them as 16bit Tiff files next. Finally, I use Sequator to stack those Tiff files.
I'd recommend trying both approaches and see what works better for you.
@@PeterZelinka Thanks for the reply, I'll give it a try.
Hey, is the orion shot tracked/what focal length did you use on that?
Yeah, that was around 600mm with a Tamron 150-600mm and the SkyGuider Pro
Hi, thank you for the tut!
I tried Sequator in the past and never felt happy with the results, so I gave it another try now and its the same experience. It does not seem to matter which selection of settings I choose I end up with a much duller and lower exposed looking image compare to view one of the images making up up the stack in camera raw. Am I missing or doing something wrong or is that the way its suppose to be?
Are you doing wide angle or deep space?
I usually don't notice much of a difference, in terms of exposure and contrast.
@@PeterZelinka Wide Angle. Since my post I am discovered that the follow works best for me. The images I important should be Tiff and not DGN. I also than have Auto Brightness and HDR set to On and my colourspace set to Linear. This yields the best results for me.
i can't seem to select all my files at once this is really annoying
Can someone tell me the BEST astrophotography lens that can mount a Canon like Canon T8i or Canon 90D? I heard of IRIX 15mm f/2.4 as well as Rokinon? Any suggestion of the BEST lens that is amazing in all aspects that can take nice shots of the Milky Way as well as Orion Nebula?
CelebrityLyrics I have no particular experience yet bu I'd say that a fast lense 2.8 and below are just nice! Rokinon is well known in this area because of their performance/price ratio. But Nikon, Canon, Tamron, Sigma lenses are all fine!
I try stacking images even just 3 or 4 and just end up with a white over exposed "fog" , is that artificial light just stacking up?
Dazza dizzy For the light frames, put a t-shirt on top of your lens and apply a light source like your smartphone or tablet on top. Take 10-15 shots with same ISO setting and speed as your sky pictures. This will reduce/eliminate the vignetting on your final photo.
Can it work with normal lens.
Why everyone talks about wide lenses
The current rage is to take a wide angle sky shot and use it as background for night time still photos.
thanks for the great video!
If I use boundary line in the Sky region, it's always red. Anyone knows how to fix it?
Cool👍🏼 Thanks Pete!
Sequator did a better job when I used my tamron lens for DSOs but now that I use the Redcat 51 Telescope, Deep Sky Stacker does the better job.
I am having problems with sequator, I went through and used the software exactly how he states in the video and my final images look all crazy or come out with the foreground out of focus. Maybe this is an effect of stacking because all of the images I am using are in focus. Also the images I am using have a lot of light pollution which I cannot escape because of where I live. Does anyone have any suggestions?
He's using an HA filter in a certain range...9 nm I think.
Astronomik. Clips into his dslr.
Is it useful for stacking macro shots?
I'm having a problem installing this program. I'm running windows 10 with an i5 processor. when I go to install the 2015 C++ the an error pops up and says something along the lines of there is already another version and it can not continue with the installation and to go to the control panel to configure or remove it. LOL there are like five or six different versions in there and I don't have a clue which one to remove or configure . I really want to give this program a go but I can 't find anything to point me in the right direction to get there.
did you try installing Sequator yet? Or are you still stuck on the C++ installation?
You could always remove those other C++ runtimes, but that might screw up another program you have installed.
Yes!!! I got it. This program is amazing. Thanks for all you're doing on here to help us bring our astrophotography to the next level.
Peter Zelinka I had to uninstall the 2017 version C++ before I installed the 2015 version. I may have to go back and reinstall the 2017 C++. But so far, nothing seems to be effected by the 2017 one not being there any more. If something does comes up, I'll know what to check forst.
If it took FITS files, Sequator would be even better. I use Sequator for my Milky Way shots taken with my Nikon, but my DSO shots (sometimes numbering in the 100’s for each target) captured with my dedicated Astro camera are FITS files. Anybody know a way to batch convert numerous FITS files to TIF files?
1:44 What do you mean "doing your initial edits"?
Edit one picture in Lightroom and then sync them all and export as tif files, then put them into Sequator
Awesome. Can't wait to try it out
do you think this will work on photos of the moon
2 years old but if you or anyone else sees this, it's a similar process where instead of taking many exposures and stacking them, you actually record a video and use a program to stack all those hundreds/thousands of frames, AutoStakkert
Great tutorial mate!
I just tried it out, it seems to work very well, but I can't find the result file anywhere... I tried several times changing the output folder, but I never find the result file in any attempt... :( do you know anything about this problem??
You specify where the output is saved to, so it should be right where you left it.
Try going through the process again, and double clicking the Output button, then navigate to your desktop. After it's finished processing, you should see the TIF file there.
If not, I'm not sure what could be going wrong
unluckly I did several times and I can't find the file neither a folder, if created in the program. I can see the file and the folder in sequator, but I can't open them. If I click on the "open" botton on top of the preview it says I need to log in in my Adobe account, I click on log in now, but it doesn't do anything. I'm already in my account in photoshop and adobe creative cloud, but it still doesn't work... that's a bummer, the stacking seemed pretty great!
@@danielefr- Change your default TIF file viewer so something other than Photoshop or Lightroom, that's why your are getting the adobe bs. If you are Windows based try the Microsoft Image viewer or IrFanView.
@@tim1398 thanks, I installed the previous version and everything worked out fine :)
When you export your RAW as TIF, do you export as 16 bit or 32 bit float?
Very good job. Thank you.
Great tutorial. Thanks, Man!
Much faster than DSS. Also has light pollution correction. Have used both on DSO and milkyway and SEQ was better in both cases.
'DSS always stops, running out of memory' - really? Mine never has even processing 500+ 16mb subs with darks, flats, and dark flats. Takes maybe 5 minutes. Maybe your machine needs more memory?
Thank You very Much Dear Master
Hi.I would like to know please if this software is able to do focus stacking?
Not that I'm aware of.
If I have to do photo stacking I normally use Photoshop
picolay.de is a good focusstacker...Rob Trek has a great demo...! I use it.
Hey Peter, Could I get your thoughts please? I have just stacked 6 images and clicked open and it just seems to run forever, should it open directly in PS? I can see the stacked file in the folder but from within Sequator it doesn't open....CHeers
Grahame
Hmmm, that's odd. I'm really not sure why it wouldn't open the TIFF into Photoshop. There's a ton of variables that might be causing that. If I had to guess, here are a few: Default program set to open TIFF files, random software bug, Photoshop version incompatibility, etc...
I would simply navigate to the folder where you saved the TIFF file and either right click to 'Open With - Photoshop' or open the TIFF once you've started Photoshop. Either way should work fine and allow you to continue with the workflow
Thanks Peter, problem solved (Y)
