Rest in peace Alyn, I’m feeling so sad and uneasy while watching this tutorial. These countless videos full of your knowledge of astrophotography are your legacy now, and we’ll make sure to spread this knowledge out in the world. Thanks for everything Alyn 🙏🏻
Oh noo what happened to him?
@@barnabasnagy9595idk. He's not anymore
@@barnabasnagy9595 He passed away a few months ago from a previous medical issue.
Rest in peace. Even now you help many people in their hobby. Thank you for everything
I just shot my first Milky Way last night. I thought of you the whole evening as I finally put everything to use that I learned in your fantastic book, Photographing the Night Sky. Stacking was seamless after following this Sequator tutorial. I have learned so much from your countless videos and was so sad when I heard the news of your passing a few months ago. RIP, Alyn. Thanks for everything 🙏❤
it always amazes me that this type of software is free!
@callum walsh He's talking about Sequator..
@absoluteunit hey, u should use photopea! It's a carbon copy of photoshop and it's free!!! just search up photopea
I know you made this video a couple years ago, but your tutorial totally helped. THANK YOU. I watched, then re-watched twice to follow along. Works perfect! I'm brand new at Night sky photography, but it's totally addicting and such a charge.
Glad to hear it's still being useful!
Sequator is my favourite program! I use it for both deep space and widefield/landscape astrophotography stacking. Glad it's finally getting some more recognition!
Gabe Sewell when I use freeze ground my ground is still blurred. Any ideas why? I am using a star tracker will this be affecting it?
Simon Pepper yes, because your individual exposures will have the ground blurred as well. the ‘freeze ground’ is for when each of your sub exposures are short, such that both the sky and the stars aren’t blurred in any individual photo. What i do is take my sky exposures and one untracked ground exposure, and then blend them later in photoshop. If you want it all done in sequator, use many short exposures so that nothing is streaked by the tracker or the earth’s movement.
Gabe Sewell thanks for this Gabe. Do you know a link on YT how this blending of the two images is easily done with in PS or LR as I don’t know how to do this... thanks
I am an old film guy, so this digital thing I am really behind the 8 ball on. I have been struggling screaming dying in fits because of my inability to understand how to get great images of the night time sky. Then I discovered through a suggestion from my missus this video. Recentlyt I took a trip to the Point Betsie lighthouse, and after capturing some shots to assemble a starline image, I saw the Milky Way just rising into the sky, so hastily I took 10 frames so that I could try this. I cannot help but say Thank you Alyn - this tutorial is priceless! Not only did the first try come out much cleaner, but colors began to emerge from the Milky Way I had not seen before. Now if I could only figure out how to get noise out of my star trails I'll be GOLDEN!!!
Yes! I have been waiting for a good Sequator tutorial and I am so appreciative that you've done it. Have you had much practice with it when you have foreground elements that protrude into the sky area in frame (trees, large rocks, etc.) - I've found it to be really finicky when you have trees in particular that have a lot of little open spaces where you can see through to the stars between branches. Sequator is great when you have a really defined horizon though, so I often use both Sequator and PS to get the job done in these cases. thanks for the info!
I've been away from astrophotography for over 10 years. Recently returned to it and so glad I found this video as I was not aware of Sequator. Thanks!
RIP Alyn. 😢😧
Another important point is you can also then push the image much further in post production. So, you can get far more detail out of the milkyway in a stacked image :)
Miss your tutorials and monthly WITNS, rest in peace Alyn
Holy crap. I love you! I just happened to find this video and less than 3 minutes in I discovered what has been causing those weird lines and patterns in my images. I always apply lens corrections as my first step!!!!!!!!!! Thanks for the info
Info was explained brilliantly. Thank you! Going to give this a go on some images I have and keep this in mind for the next trip out into the night sky. Seems much better (quicker and less hassle) than the Photoshop way.
I have used Sequator a few times. Seems to be my “go to’ for milky way edits. This is one of the best tutorials on how to use Sequator . VERY WELL DONE Thanks
Great tutorial. Hint: you can use you mouse wheel to make the brush bigger or smaller - something that wasn't included in this video.
Great tutorial as always. I would like to see a tutorial on multi-level astro panorama from planning to shooting and finally processing. I have a Canon 77D (1.6x crop) and my widest and fastest lens is the 24 - 70 f/2.8 L ii so I have difficulty in squeezing foreground and sky in a single frame. Keep up the good work 👍🏼
giddy-up #1
I've been using Starry Landscape Stacker since last year when I saw it on Lonely Spec. It's a fantastic, easy to use and fast program.
Excellent tutorial Alyn, thank you for sharing your knowledge and work flow....Cheers mate..
OMG! Just as I’m getting into astrophotography I find this video. Brilliant stuff
Thank you Alyn. I followed the tutorial and managed to improve my pics massively! Will now aprehend my phototaking keeping this in mind. Thank you so much
Havent done this for a while. Took some shots last night. Here I am again :)
Love your videos Alyn. I am a relative newb to landscape milkyway photography, but your tutorials have been invaluable. I have ordered a copy of your book too. Thanks bud for all your fantastic work. It really is inspirational.
That one unlike is from smart phone photographer i think. Haha
that 19 unlike is from smart phone photographer hahahahaha
Not all people can buy good camera and pc :))
Twat.
@@paulstone22 Paul mate don't be like that
@@extreme_5137 :)
Great explanations thank you so much!
How do you manage to get the tent in the foreground sharp at f/1.8 while focusing on infinity ?
Do you take extra pictures (with the same parameters as for the Milky Way) but with the focus on the tent, stack them and blend it with the Milky Way stack ?
Or maybe you stand far enough from the tent to still get it sharp with your given focal lenght and aperture ?
I think He is shooting using a wide angle lens and seeing the composition i can tell the distance between the tent and camera is sufficient to get everything in focus.
regarding the funky patterns. Thanks so much I used to get that all the time when stacking star trails pics and I never knew why!
I like to take my sky exposures during a new moon and return on a full moon for the earth portion using the same lens and angle. I track the sky exposures and stop down two stops for nice tight stars. My land exposures are non tracked with low iso and underexposed as my camera is invariant. For ease I use long exposure noise reduction on the land exposures. I use topaz remark to combine both exposure
Glad to find you some time ago. Finally I watched this tutorial and I am so glad. Very good step by step guide! thanks
Thanks again for this tutorial Alyn. Its a great program but not the most intuitive in layout. It just zipped through an 8-image MW stack and came out terrifically. Cheers.
When I used Sequator with my original A7r, it worked great, but when I moved to later Sony 42 MP sensors, the results were extremely desaturated. A friend with a Nikon D850 told me he had the same experience with his 45 MP sensor.
Brilliant and very helpful. I now have Starry Landscape Stacker so I hope some of this knowledge is transferable.
In regards to future vlogs...perhaps one on timelapse? In particular, the 180 degree rule and whether that is needed to astrophotography? And in the daytime (clouds, moon, sun) tips on interval times and shutter speed :)
I'm looking to do timelapse workshops in South Wales in the near future so I won't be doing a video on it unfortunately. I will be doing a video about motion timelapses of the milky way next month though
Thanks for a great tutorial. I gave it a whirl, and it has taken my MW photos to a new and higher level, thanks!
I've already tried the software and it really works well, but a learned a few things anyway watching this tutorial. Great video as always Alyn!!
I've used it and yes it works well. Thanks Alyn for the explanation on some of the options you can use/not use, very useful. Just can't seem to get Sequator to work on my PC id I export as TIFFs. JPEGS it works with but not TIFFs :-(
Hmm that's strange 😕
@@AlynWallace yes sigh. Tried it again and it starts going wrong when I try to do the irregular mask. Screen goes black unless I reset then same thing happens. If I then stack I get message it's failed. Works OK with JPEGs..... Wonder if any subscriber has any tips?
nice one alyn , just started using starry landscape stacker a couple of weeks ago , very useful tips in here that I'm sure will apply to that too , will put them to use when I return from la Palma on the 6th
Very informative Alyn and as always your knowledge shared through your channel is a great benefit to many people
Thanks Alyn. That was a little fast in the middle but I will watch this a few times while sitting in front of the software. Much appreciated
Excellent video Alyn, invaluable information!
I've used the photoshop technique before following Ian Norman's guide. It felt like it took forever. Gave me a super clean finish, but a long process to get there.
This will definitely speed up that process!
Cheers Alyn, keep up the great work bud.
Great video as usual Alyn. Like yourself, I have the moveshootmove star tracker (very handy unit). Is a tracked single image for the sky and then blend the foreground better than a stacked image? or Is it worth stacking some tracked images of the sky?
Great information on sequator. Very helpful thank you
I use Starry Landscape Stacker and I've started to get that strange pattern you showed. Now I know why. I will redo with lens correction off. Thanks.
Rather late but thank you for sharing this! ✨
Thank you very much this is great.
I recently was having issues processing a set of images I had been looking forward to capturing, and of course who is the first person I turn to? RIP Alyn.
Thanks so much for this, I have a Nikon d300 so my images are very noisy and this really has made a huge difference 😜👍👍
Really great informative video Alyn. I love Sequator .. and it's free ... can't ask for more than that I reckon. Richard
perfect tutorial
4-5 Images yields good results
6-8 yields great
And 8-16 yields excellent results. So I guess around ten for longer exposure and 16 for a shorter one
Very good tutorial.
Bloody hell, what a difference in the two images......shame there isn't an app for tablet users..thanks for the share 👍
FYI: You can run Sequator easily on a MAC using Codeweavers Crossover for Mac
www.codeweavers.com/compatibility/crossover/sequator-154-64-bit
Excellent tutorial, thank you!
The software is brilliant! Does the Mac compatible s/w have a similar workflow and quality of output? Thanks for sharing.
Just got the Mac one, learning a lot.
Thanks Alyn, good to know i'm doing it right! Do you do any further noise reduction after stacking in Sequator? Your images always look so clean and crisp.
Thank you!! Very interesting and useful!
Excellent Alyn
Brilliant Video.
RIP mate
Great video. How many dark frames do you usually take?
Great tutorial 👌thx for posting
I tried this after watching earlier in the week. I need to have another go whilst watching as I might have missed something.
Had my images (9 of them) that were fairly well exposed. Once stacked, it exported probably 3 or 4 stops darker. Not sure if I had to click something else.
I'm looking forward to shooting again and trying this out with newer images.
Great tutorial. A highlight around the software's Check Boxes and Radio Buttons, etc would be a plus :-)
Hey Alyn great vid. Hoping to see a tutorial vid for the SIFO star tracker...
thanks mate this is super helpful. i cant wait already to go to the sahara desert in morocco this summer!! cheers a lot!
Thank you, your images and videos are inspirational.
Great explanation and easy to follow!
watching while taking my milky way mod focal range light frames 😘👍👍🏆❣❣
thanks a lot mate. It is very well explicated
You just upgraded my pictures in 1 tutorial! Thanks alot!!!!
Great and helpful video Alyn well done!
Hi Alyn. I've really been enjoying your videos and I'm learning TONS from your fabulous explanations and approach. Keep up the great work. Thanks! :-)
Thanks Alyn, that's really helpful and explained clearly.
Ha ha needed a refresher course on this. Just the ticket bud cheers.
very useful and clear, thank you brother
Great tutorial Alyn.
Thank you so much for this very useful video. Love your channel and content and thank you for sharing your skills and knowledge with everyone
I really struggle with artefacts in Sequator when I use it to blend my images. I am not sure why am having that issue but it's got to the point where I'll align my images in Sequator and then stack and blend in PS
It happens the same to me :(. Did u manage to find a way to get rid of them??
@@nelsimaru nope!
Like I mention, I aligned in sequator only and then stack and blend in Photoshop using a smart object median blend.
Currently I actually track shots now so haven't needed to align and stack a milky way shot in a couple of years now
@@ChuckleChuckleVision thx mate. I’ll have to learn some Photoshop stacking then. Good luck with your shots buddy
@@nelsimaru it's honestly not difficult :)
Such a helpful tutorial. Thanks
Hi Alyn. What a great piece of software ! The difference in the Elan Valley shot was amazing. Looks really easy to use so I'll have to get the app downloaded to my Mac. Thank you so much for sharing. One question if I may - is it expensive to get a camera astro modded?
in the beginning u open up ur editor and make some changes to the raw file . is it affecting all the image layers at once or did u just edit one foto ?
Thanks for a great video. Aside from the basic lightroom adjustments before stacking - what if any adjustments do you make after bringing the stacked image back into lightroom?
Thanks Alyn. I am trying this just now. Will post on my insta soon. Thankyou.
Hey man, great tutorial. Been into astronomy and photography since I was a child but I’ve only just started astrophotography. Crazy, I know. Is there a stacking solution you’d recommend for Linux?
Perfectly explained, thank you so much
Really enjoy your videos, thx ☺
This was extremely helpful, thank you so much!
Cool tutorial. Thanks.
Great video Alyn really enjoyed those keyboard shortcuts you threw in there as well! So although you highlight the sky area from the software, Sequator still processes the whole image?
THANKYOU...
Thanks for a great video,love doing Astro, this will help immensely.
Another great vlog Alyn, can you tell me over what time span do you do your time lapse images, and how long between each shot?
Very helpful and informative video. Fantastic as always.
Alyn - I'm really in testing waters stage for Astro. So great video and really helpful for people like me. My question to you however, is in the first edit I see the finished image seems to have a tiny bit of trailing of the stars . Would that be something as a result from Sequator or were the raw images in that state in the first place? Sorry if it sounds like a dumb question.
Great tutorial! Thanks for sharing!
This is a great tutorial vid. Thanks so much
Great video Alan :) But who is better for noise reduction: Sequator or PS median smart object stacking ? Cheers mate.
Hi Alyn, thanks for your tuts. Useful!!!
Just a quick question: I've noticed the yellow color of lights in the tent photo (and other pics in other videos). Don't you use a filter like nisi clear night or haida clear sky?
Thanks for your precious reply!
What if you use an star tracker for even longer exposures? In that case, the foreground will blure and move from exposure to exposure. What would be your recommended workflow. Take other set of exposures with the tracker stop to stack foreground exposures and sky exposures separately and then merge them with Photoshop? Thanks
Hey Alyn, great work! Do you ever shoot in North wales/snowdonia?
