I have watched a lot of Astrophotography videos and I really like the way your pictures come out. I have noticed in quite a few other photos from other photographers where the stars are either all blue, all red, or all white. And many look so modified to where they almost look fake or stylized. With yours, they vary in color which I think is natural and the way the photo should be. My only Astrophotography experience so far is some very amateur Venus transit of the sun videos and only hope to one day take photos as good as yours. I realize you are trained for graphics design but many of us can only learn by watching you do this sort of thing, so thank you for sharing your knowledge.
A little Processing tip i use quite a lot is using a high pass filter. Under filters - Other - high pass. This allows you to bring out and sharpen lots of detail inside of the nebula or the target you are imaging. I usually go at around 50pixels then set the blend mode to soft light. I then create a layer mask, invert it then i scribble in the parts i want to sharpen. Hope this makes sense and helps.

I'm stopping at 11:57 to comment. I spent several hours last night going over another tutorial online because I could NEVER get my image to look much better at all playing with the levels. When I pulled your RAW file in, it looked just like mine so I thought my display must be too cheap to see the changes. Now I'm looking at an image that is almost exactly like the one shown on your video (I have the trial CC version and haven't purchased any plug-ins). I'm astounded at how well the image can be enhanced using just a few basic adjustments. Thank you SO much for not only putting the vidz together, but also taking the time to do detailed write-ups.
I know you get this type of comment a lot but your channel has been great for keeping me occupied while I await the delivery of my first proper imaging rig. Thanks a ton. Your vids are top notch.
I should like to thank you for your work in posting this video. It has been very helpful to me --- an astrophotographer newbie --- in learning. I believe toward the last you said this was your first astro tutorial video; well, ..., I would not have guessed. You did a great job. I have gone through literally 100's of other videos (Photoshop, PS plug-ins, Pixinsight,...) and this video has been the best for me. I now have paid for and downloaded the Astronomy Tools Action Set; installed them in my PS CC 2018; and plan to continue to learn and apply my knowledge to images! Again, thanks!
Yeah, I second this. A fantastic video, thank you. Being able to teach is a very different to having the technical skills. Very few YoutTubers understand how to communicate clearly.
Great tutorial. I really learned a lot. I like how you used the color selection tool while doing the layers to pull out the pinks from the nebulosity while keeping the background blacks stationary. That made a huge difference. I can't wait to do some re-processing on some of my images.
Ever since I found your channel yesterday, I have to say this is my favourite astro-photography channel. Very nice delivery and excellent information. I especially loved your equipment video. You have shown us you can get great results and you don't need top end gear to start out. All the best and thanks Cheers Jim
Thank you for a series of fascinating and enlightening vlogs. ive just started with astro-photography and i've no doubt your videos will be immensely helpful . Thank you .
Many thanks to you Trevor for this amazing channel and for what you are doing!!! Your videos really help me to undertand basics of astrophotograpy as beginner.
Pure awesome.I have the telescope, but no cameras yet and tracking software. I am only interested in what can be possible for now. I do hope to get to the point I can create my own photos! Thanks so much for this tutorial.
thx for that ! wouldn't have known how to get going with all the editing. Would be great to see additional videos when you refine your technique or discover stuff :).
Greetings from the U.K. ... Great video as always, love the stuff you do and the images you get 😊... Please could you just explain what ‘Light’ and ‘Dark’ Frames are, and how do you go about taking them? Thanks 😊
wow! i am so glad I found your channel! Your photos/videos are quite inspiring. I very much am enjoying gathering information through watching your videos, I soon hope to dive head first into the world of astrophotography, just gotta save some money first! I especially find these videos of the image processing/editing to be very helpful and insightful. DO you have any videos showing tutorials on the different programs you are running during/at the beginning of your viewing/shooting sessions?
This tutorial is awesome for DSO's. But, I got one for you that I think would help a lot of beginners like myself: similar to this, but doing a widefield shot of a constellation, such as Orion. Orion has a lot of features hidden that could be pulled out. Trying to follow this after busting the nifty fifty out on Orion, and it's not working out too well, unfortunately.
Well done, I immediately bought and downloaded Astronomy Tools, but I ran into some confusion with the zip portion of it. I actually downloaded three versions and then deleted two of them yet they still show up on the Photoshop window. I'm tempted to delete and start over by downloading the recommended version for my set up, hope I don't loose my subscription, but if I do I suppose I can clear that up with the Astronomy Tools people. One other thing I noticed. I don't know if your version is different than mine with updates and so forth, but my Astronomy tools window doesn't have the row of symbols at the top of it like yours does, mine lists history and actions only. Thanks again for tutorial, I learned a lot from it.
Thanks heaps! Just trying to learn these things, and seeing somebody who knows how to do it helps immensely. I'm using GIMP, though, so all the plugins may not be available. I also enjoy your other videos. Keep up the good work!
Total newbie to astro photography so I was interested to watch this. I was bummed when the actions and plugins showed up though! Would it be possible to do this video without them (i.e the hard way!) so we can get similar results and understand what it is that the actions etc are actually doing? At the moment all this is still like sprinkling fairy dust (well it is for me anyway). 😀 Really appreciate your efforts to educate us with your hard earned knowledge.
Outside of astrophotography, I found Neat Image to be very good at reducing noise, especially for artwork type of image, either if you want an invisible filter or if you want to see the obvious effect of the filter. It is also a calibration process for each iso level of the camera. It should work on a stack, because noise does not change shape, it is reduced by the stacking, so I feel it would work only you'll have to reduce the power of the effect. This filter works by separating first light and color, then addressing each noise frequency. It's very good at removing the color blotches you get when stretching the dark : in that case go up one iso level, because by stretching you did the same thaing as if the shot was made one iso level up.
Great tutorial, I'm an experienced photographer 1st but very new to digital Astrophotography. A few questions. I was surprised you didn't use layers so you could experiment without wasting or losing a lot of work if something went wrong. Same with often saves, which maybe you are doing. And finally saving the edited version as a full size .tif or PSD in case you ever wanted to print a large image, you would still have all of your layers & work available. Then reduce it to Web Sized or smaller print .jpg's. Or perhaps this wasn't an important image to you. Since this is now a 4 year old video I'm curious, do you ever use the Editing tools in DSS? I'm new to it and not sure if I should be balancing the color channels. I don't notice any difference when I adjust the saturation or curves adjustments in DSS. Thanks for any feed back if you or anyone else sees this post. Love your channel. I've learned so much from it, even though you are literally light years ahead of me. I'm just using a non modified Nikon D7000 with a 35 & 50 mm prime, Tokina 11-20 2.8, and 2 kit zooms Nikon 18-105 5.6, and a 55-200 5.6. I also use and love my iOptron Skytracker Pro and an old 70's vintage Celestron C8 on a Wedge Tripod. I've become very quick to polar align the iOptron Skytracker Pro, but not very good at Aligning the C8. What is a good DSLR lens to photograph Rho Ophiuchi? Thanks again. Dave in Eastern, PA
Thank you so much for the tutorial. I started watching your video just recently, and already learnt quite a lot about equipment, imaging and processing. Your contents are quite on point so they are extremely easy to grasp. However I have a quite fundamental question as I am just starting to learn deep sky image processing. As I try to adjust curve, the noise tend to exaggerate. Those greenish grains starts to appear as the image gets sharper. Was the noise there in the first place, or was it introduced during processing? Thanks again for those wonderful content.
Thanks so much for this. Going to look for a Mac alternative to DeepSkyStacker. Also, for the vignetting, would it make sense to use the vignette adjustment in the Camera Raw filter?
FYI Colormancer is no longer free. It's $65 USD for the full version. There is a demo but it leaves a watermark that's very faint. The rest of the tutorial helped me a ton with an image I shot under moonlight recently!
Sir i have a problem in opening my images in DSS I captured M31 using my telescope and mobile phone camera The jpeg images are opening on dss It is showing "can not open multiple files from this folder" Please help sir🙏
Great video! I am not familiar with all the versions of Photoshop and wondering which version you are using. Also, is there a version that is better than the other?
Hello. I’m new to astrophotography, and just have a simple DSLR camera with a wide angle lens. I was going to stack a lot of 10 or 20 second images to try to bring out all the light, but since my camera does not move and the stars do move, (well the Earth does but you get my point I assume) will it stack them in different spots and not work, or will this program align them? Any tips would be greatly appreciated.
This is the simplest tutorial of yours. The composite one s just too much going on and too complicated post process for some people who just want to simply do only 1 set up for shooting. Thanks a lot for this video
I downloaded and installed the Freeware Boundary Noise Reduction plugin but when launching Photoshop, it prompts that the plugin is not available. The system info log shows that it failed to load.
you've probably already looked this up by now, its because dark frames have the lens cap on. Same exposure, ISO, temperature just with a lens cap so that no light can get in to the sensor. This helps eliminate hot pixels created by the camera.
If I don't have a tracking mount, can I take many more pictures at much faster shutter speed instead? Would that yield the same result? Also, can you get some decent result with a 200mm telephoto lens on full frame camera (no telescope at all)?
I use a 300 mm lens on a aps-c size sensor, and i did 100 1 sec lights on the orion nebula. it looks great even without a mount. yes you can, but if you want to get pictures of smaller objects you should at least get a lens with more focal length.
I admire your enthusiasm and dedication as I am also a keen enthusiast within the astronomy field and I am eager to learn Technics within the astrophotography field, but I thought this broadcast was based on the science of astronomy and astrophotography and not computer science.... I could go outside and shoot with a basic £25 camera and use a software programme to enhance my image.... surly this isnt astrophtography . I swear this is not a dig but merely a genuine question based on what ime seeing. I would love your feedback just so I can learn something new... Thank you for all your TIME and hard work...x
+Mr. Astro Thank you! For this shot I did not use dithering, just normal guiding. I used to use Canon EOS Utilities for camera control. I now use BackyardEOS, and enable dithering when taking my light frames. Cheers!
+AstroBackyard Thanks for your reply..I am confused ..is it better to use dithering or not.. also, is there a different between stacking the fames with dithering and without?could you give a hint.. Thanks :)
+Mr. Astro It is said that dithering should decrease the amount of noise in the final stacked image because the randomization of pixels on top of each other. I haven't noticed a huge difference in my images since dithering to be honest. You would only notice the difference when stacking the frames manually because each frame will have shifted slightly. I use Deep Sky Stacker anyway, so it registers them for me. All the best!
What kind of telescope would you recommend that's somewhat affordable and can see these fairly clear? Does the aperture matter more than the focal length?
For visual use, get a dobsonian reflector. Big views, big aperature at a modest price: astrobackyard.com/buying-your-first-telescope/ - For Astrophotography, a high quality, small APO refractor such as the Explore Scientific ED80 use for this image.
This may sound stupid but tI've just started to learn astro., and I'm really newbie, so I can't understand how did you take those photos.. Did you use some kind of a telescope ? And assuming that the Earth is rotating, how is it possible that every photo you took is perfectly aligned and you have the same frame ? Is it some kind of star tracker ? Lots of questions but I hope someone would make this clearer to me :) Thanks a lot !!
Yes he is using a telescope on a tracking mount. Even with tracking you still need to align the images. I think he uses Deep Sky Stacker to align and stack his images but you can do it in photoshop as well.
I have watched a lot of Astrophotography videos and I really like the way your pictures come out. I have noticed in quite a few other photos from other photographers where the stars are either all blue, all red, or all white. And many look so modified to where they almost look fake or stylized.

Enthralling material, but that music which used in your movie so intriguing too. Can you tell me what group or author is? Thank You.
Carbonis actions changes image to 8 bit. You need to delete the step from the actions to avoid loss of details
Would be useful to know why you aren't using flats and bias. Also what happened between 26:00 and 26:05 ? Looks very different.
It's very useful for such a beginner like me
So here we go-took first pictures last night...not sure if we really captured anything but will give photoshop a try!
this was great, would like to see more!

+David Micheletti For this one I used an 80mm apochromatic refractor telescope as a lens. The Explore Scientific ED80 to be exact.
What kind of telescope would you recommend that's somewhat affordable and can see these fairly clear? Does the aperture matter more than the focal length?
For visual use, get a dobsonian reflector. Big views, big aperature at a modest price: astrobackyard.com/buying-your-first-telescope/ - For Astrophotography, a high quality, small APO refractor such as the Explore Scientific ED80 use for this image.
AstroBackyard do you know if I can attach my DSLR camera to that scope?
Yes, with the correct adapters.
This may sound stupid but tI've just started to learn astro., and I'm really newbie, so I can't understand how did you take those photos.. Did you use some kind of a telescope ? And assuming that the Earth is rotating, how is it possible that every photo you took is perfectly aligned and you have the same frame ? Is it some kind of star tracker ? Lots of questions but I hope someone would make this clearer to me :) Thanks a lot !!
Yes he is using a telescope on a tracking mount. Even with tracking you still need to align the images. I think he uses Deep Sky Stacker to align and stack his images but you can do it in photoshop as well.
Thanks man ! That's what I was thinking of, and after a while it became clear to me that tracker is a must for shots like this one :)
