My Complete Astrophotography Image Processing Workflow

[@dankahraman354]

I just did the 3rd Arc Sinh stretch and WOW..can't believe the detail it has pulled out. I am liking this.

[@Bills_APCh]

Aaron, did you see Mark’s Shelley use a grey multiplier and divider layer to apply arcsinh stretching in photoshop. Also calibrating your lights with flats and darks would make your processing easier!

[@kk-GUK]

your videos are great, thanks for taking the time to help people.

[@AVAstronomy]

Glad to help. God bless!

[@JennCoutu]

Thank you so much for this tutorial. This was super straight forward and easy to follow.

[@ChucksAstrophotography]

Very nice end results!

[@AVAstronomy]

Thank you Chuck!

[@blackpanda7612]

Looks like Control + J (= New Layer) is the most important step in processing. Definitely something I'm going to make a habit of using. Really awesome tutorial. Probably the best I found so far on youtube. It's videos like these that give us newbies a huge platform to start from as this kind of processing astro images can be daunting to anyone looking to get started in this hobby. On behalf of all newbies to this, I want to say thank you very much for taking the time and effort to help us get started on our journey.

[@AVAstronomy]

LOL! yes I use CTRL+J ALOT! Glad you found it helpful. Once you learn the main tools for your workflow it becomes much easier. Keep at it. God bless and clear skies!

[@johnambrose4093]

Excellent tutorial! As a beginner with photoshop I get very frustrated watching videos from those who zip thru the shortcut commands leaving the viewer scratching his head as to how the new menu was invoked. You gave GREAT step by step instructions on how to use the shortcut commands. One suggestion, when you bring up a new enhancement to make and bring up the menu to make the change please give a little explanation WHY you are making the change. Sometimes it is hard to "see" the before and after change on a video and knowing WHY it was done would make it easier to know for our own images. Anyway, excellent video and thanks! Update 12/11/20 - I finally got thru using your step by step onto your example of M45. It was great following along my steps while you do your changes on the video. Great learning tool for me with my limited skills of photoshop. One thing I did do different is to use lasso and select inverse and then run gradient Xterminator to reduce the color shifts outside the nebula. Makes a difference. Thanks alot. I WILL be using your steps on my own projects now. Keep up the good work!

[@AVAstronomy]

Thanks John glad it helped you out

[@johnnyredfireastroimaging5266]

I don’t noise correct as much anymore since topaz denoise ai. As for the vignettes, flat frames help. I don’t dither bc as you see there is a lot of cropping post processing, so calibration frames do help

[@AVAstronomy]

I’ve been wanting to try out that topaz Dennis’s. I’ve heard a lot of good things about it. And I agree if you don’t dither calibration frames are necessary. I’ll be doing a follow up video soon that will look at an example image that has calibration and frames and the same image without. My argument is that with solod dithering and a cooled camera there is enough tools in post processing to eliminate calibration frames. Maybe not for every situation but I believe for most. Should be an interesting experiment. Thanks for watching. Clear skies and God bless!

[@jamesgodfrey9348]

Thanks Aaron! Just getting started and I really appreciate the insight into your workflow.

[@AVAstronomy]

You're welome James!

[@GrowingAnswers]

I was using the same stretch methods and with the arc sign curves for a while. Until I found another tutorial with a different method, I was not getting the best results. And I didn’t realize it. I started using a multiply and divide layer with arc sign stretches which preserves color and prevents star bloat altogether without using a mask at all. I only end up doing 2-3 arc sign 10 stretches before it maxes out potential. I’ve been using that method and brings out so much more dust and detail and without losing anything or bloating stars. I’d link the video, but I don’t want to redirect your viewers. If you want to see it, let me know. I haven’t seen any other methods like it.

[@AVAstronomy]

That sounds great. Sure, I'd love to take a look at it. Always looking to improve.

[@GrowingAnswers]

@@AVAstronomy where would you like me to share the link?

[@AVAstronomy]

@@GrowingAnswers I found it. I've actually seen this one before. It is a very good video, the only thing is there is a trade off to this method. While it does help minimize star bloat it can completely blow out the core and surrounding portion of the stars leaving a harsh core. I think it will fair better with images that already have smaller stars but for images like M45 this method didn't fair as well for me. I'm definitely going to experiment more with it on my emission nebula data.

[@GrowingAnswers]

@@AVAstronomy cool, yeah the key thing with that is setting the black point more precisely before each stretch and only setting levels and curves from the multiply layer. Typically what I’ll do is use that and and stretch one less time and then either do a star selection or use the star removal program and then finalize the background. Re-adding the stars with that persons method is also really easy. If the stars are added as another layer it’s a little easier to minimize them by just by setting a lower blend percentage. I’ve only really found the issue with stars as you described, with my nifty 50 lens. Using that method with pictures from my scope I haven’t seen any issues. It tends to have a bad reaction with more coma or aberrations around stars mostly. Certainly not a perfect method and other methods need mixed with it on case by case basis.

Hi Marc, I actually was using my maksutov newtonian scope. This was 60 x 4 minute subs with the QHY168C. Bortle 5 ish / yellow zone.

Hello Aaron. Nice workflow Aaron. Siril is very good. I would like to examine all the processes. It seems easier to understand than Pixinsight. I wonder why don’t use non destructive workflow by using groups of layers, clipping masks, and ctrl-alt-del-e to create a new layer on top instead of stamp visible. I also preferred the image after Siril to the final image in Photoshop. The stars in final image looked more like noise and grain to me.

[@AVAstronomy]

Haven’t used Siri yet but hear it’s good. I don’t stamp new layers that much as the file sizes I work with are pretty large and it makes the program lag a bit. Plus, I can always revert with the history tab. Maybe one of these days I’ll get around to trying out Siril. Thanks for watching.

[@MrSpike2450]

Just brilliant thank you, should i still go image/mode/16 Bit/exposure and gamma ?

Thank you! yes, you want to be in 16bit mode but it should default to that. If it doesn't then you would make that change.

Aaron another problem I am having is that my version of PS doesn't have the same format and I know I am missing a lot of plug-ins.

[@astroimager3010]

Excellent video. Looking forward to your calibration frames analysis. Late in the video, when you are using Camera Raw, consider using a combination of clarity and dehaze. You only need a little of each. And, although texture and luminescence sliders seem to work in opposition, try decreasing texture to soften the image by one or two point along with the color noise slider.

[@AVAstronomy]

Thank you! Yeah, should be an interesting experiment.

[@dankahraman354]

Switched to another computer and downloaded PS CS6 to it..almost completed entire lesson but for some reason Camera Raw is not part of the Filter drop down menu...I will have to download a full version. I have the original keys...The way you use hot keys make PS much easier than I even imagined it would be. I have spent over 10 hours wasting my time on the other desk top..getting very harsh stretch artifacts in addition to certain keys not being available...even the Levels black point and the histogram didn't match yours...with the current desktop I switched to, much better results...go figure! Yes I had to load the Gradient xterminator and the Sinh stretch curves anew to this computer. Both are Windows 10 computers.

[@AVAstronomy]

Hi Tobias, The total exposure time was 4 hours. It was 60 x 4 minute subs stacked in DSS with no calibration files. When you stack an image the data is linear and to the left of the histogram. This is why it's dark after being stacked.

[@jmclauren]

@@AVAstronomy Hi, thanks. My stacked ones i DSS doesn’t get that dark at all. I am using calibration files though. Are your single RAW-files darker to or more closer to a middle histogram exposure?

Great video! I used your tips on some of my images and it really improved the overall quality! I have a question: the "stacking artifact" that you refer to at 8:25, what is it a result of? I do some imaging every now and then and I find that the longer the total exposure of my image the more I see this stacking effect. It's not much of a problem because like you say, just crop it out. But I was wondering whether it has anything to do with polar alignment or tracking issues.

Thanks! Well done. Just started to work in astrophotography and your video is a great sources. I am starting with M42, is this a good workflow to follow for it?

[@T-Bear]

Nice tutorial man, tanks 👍But why a destructive workflow. Why not stamp new layers (ctrl+alt+shift+E) as you go along instead of flattening every step and thus make it impossible to go back if ned be? The image file Will of course be huge, but well worth it in my opinion.

[@AVAstronomy]

Hi Torbjorn, thank you and yes I totally see where you're coming from and can see how the workflow is less "destructive" however, you can always back track with the history tab and my system doesn't have a huge amount of RAM so for performance sake, I flatten the image as long as I know I'm happy with the result from that step. Thanks for watching.

[@EverydayAstro]

Great video, Aaron. Always love seeing other peoples workflow as I always learn something! I am usually far more aggressive with the arcsin (using 300 or even 1000), though I wonder if that's because I am a good boy and take all my calibration frames so I can get away with more... 😉 Looking forward to your comparison video for that!

[@AVAstronomy]

[@rossc383]

From a tutorial to another tutorial it seems to me that arcsin curves are applied incorrectly. The author provides two methods, a layers and an adjustments method. If I understand the idea correctly, it is not enough to just apply an arcsin curve to preserve color, you have to do multiply and divide steps on luminance. Correct me please if I'm wrong

[@AVAstronomy]

Hi Rostislav, yes, if strictly following the instruction on cloudy nights forums, then you would use the multiply/divide method. I personally didn't like the effects that method was having on M45. I think it's better suited for photos with smaller stars already. Images with large bright stars suffer from a harsh edge/contrast on the stars that I don't particularly like. I did find, however, that simply applying the arcsin stretches still helps to preserve star size and color better than doing standard stretches.

[@KYREKING]

Really really really nice video! What about the exposure that u took for the image? And how many of them? I know that u didnt took calibrating images like darks or flats but how many light brother?

[@AVAstronomy]

Seeing that you are imaging in bortle 9 skies. You will definitely want some narrow band filters like the optolong l-enhance filter. You will also need to mod that T5 or get a one shot color camera. If you’ve got deep pockets then go for a mono camera. Those do great for narrowband work.

Hi Aaron! Cool tutorial, I already incorporated a lot of your techniques and they have helped me tremendously! I think I notice you have the astronomy tools action set and you did not used it. I recently got it and it has lots of stuff but I really do not know which tool to use on which image type, like I use the reduce gradient and reduce space noise, they are cool but it dims all my color and I was not able to use the lasso tool like you do to protect, it ignores it. When do you use that tool set, for what image type and which ones do you use? Clear skies! @eyethesky

Hi Edwin! Yeah, so I use to to use that action set quite a bit but not much anymore. About the only action use in it once in a while is the “enhance dso amd reduce stars”. But honestly, I find my newer workflow more to my liking.

[@michaeldonaldson4334]

Loved the video... seriously dumb luck I found a way to use your process but use the color selector to remove the colors on the outside. • Lasso the main target area; anywhere you don’t want to change • Top Middle short cut button or Go To: Select and Mask o Properties window should pop up o Set Feather and Smooth, both to 20 o Click Invert • Go To: Adjustments - Saturation; open mask o Or… Layer - New Adjustment Layer - Saturation o You should have an eye dropper tool as the pointer • With the eye dropper… select the bad color o The saturation menu should change from master to a color close to the issue color o Desaturate the bad color until it is the way you want it o You may have to select multiple colors • Optional… Select the previous layer and miss with saturation and curves to tweek • Flatten you image

Something you’ll learn as you get into this hobby is that everyone has their own methods. Everyone and their grandma has a method on how to do this hobby. I have a workflow that works well for me and produces solid results it doesn’t mean it’s by any means the only way. If star tools and APP work for then good for you sir. Stick with that. All I’m doing is sharing with others what has worked for me. Maybe check out astrobackyard, astrofarsography, or astroaddict. They may have some tutorials that better fit your needs. Best of luck.

@@AVAstronomy I don't mind. I am beginning to like it. I have the sinh stretch curves installed as well as the gradient exterminator. I was always curious about PS and with your approach I will learn it. Don't mind my griping. You have much to offer. I am half way through but I will have to start over again tomorrow. It is good. As I stated before I am extremely curious about your no calib. files approach to get good results.
