Some good tips. Had been only using in Pixinsight. Recently installed on PS and looking for just this. Separating the stars from the starless. In order to edit background and not the stars.

By reducing one of the image by 50%, you are tossing away 1/4 of the total exposure time. Wouldn't it be better to use the stacking function in PS?

Please continue your wonderful tutorials on processing astrophotography

I have a noisy background around an image of the Jellyfish Nebula I am currently processing. I have been wondering about a layer to help clean up the background. This video has given me some ideas.

Great tutorial, Craig! This is very helpful for us shooting in light polluted areas. I’m always fighting trying to get an even background and remove all the blotchiness and color gradients. I really like these short tutorials. Please do more. I would love to see one related to noise removal after applying this technique.

Very useful technique

A nice way to remove the junk on the background, very useful video THANKS Craig

As usual, excellent tutorial. I think you really highlight things that would be extremely difficult to do in pixinsight, and you've made the point several times that photoshop and pixinsight are really synergistic. Photoshop can be daunting, but you have a nice consistency with your tutorials, and I'm glad you take us through step by step.

Great video, thanks.

Thanks so much for this. I think this is some secret magical sauce knowledge you shared there.

This is way too complicated, there must be an easier workflow than this

flats are definitely NOT universal. most of the motes you see in an image are on the camera window itself. the dust on the objective is in the infinity space...

Brilliant video. The more I watch your channel, the more tips and tricks and techniques I pick up. Keep them coming please!!!

When you connect the eaf belt to the lens focus ring, where do you have the dial set to on the camera? Seems that infinity focus is all the way locked to the left. Just picked up this lens and will be running it through ASIAIR plus. Thanks

gm craig, i jumped back into this tutorial again to finish the pickering triangle. when the editing is finished, what is the best way to save the image and you know my ultimate goal is a print.

You're the man!

I've seen your pictures on the PI group on the Facebook. I love your work. Thanks for letting us peek behind the scenes :)

Yes craig, I do. What are the specs on this scope. Is this a customer’s or your new telescope

Wow

Very useful video! Thank you! You should really do one on computer monitor calibration.

Craig, very interesting tutorial, how would I change pixinsight to adobe rgb. In my amateur photography experience, I have always set my cameras to adobe rgb color space. This brings up another question, can you change color space in the Astro cameras.

Thank you for another excellent lesson. I saw the video that you were referring to, and while it had value, this goes into a much better explanation of how to utilize color space. You always do such a great job.

Excellent video, thank you! I keep learning more and more from you. I admire colors in your images, especially red which is blood like, but still pleasing and fits the other colors in the image. I am still not there and I cannot produce the colors I like. Moving sliders is a skill that comes with experience.

Great tutorial, Craig! This is very helpful, can’t wait to try it myself. Love your videos!

Thanks for this, as I have been wondering what your method was for adding LUM back in. I have been recently been following your ideas, so have been doing inital work in PI and then bringing tif files into PS for further development. I have only just finished an image where I took tif files back into PI to add the LUM channel. Now I can see how you do it, so next time I will try this method.

Thank you for taking the time to explain this. All the best in 2025! Clear skies!

Nice process

Wow! This was a great tutorial! My PS skills are still very basic, and videos like this are immensely helpful. Cheers!

Thank you Craig for another great video! I normally do Lum in the middle of RGB group and global adjustments and I put it into Luminosity blending mode, but I leave RGB in the passthrough blending mode at the bottom of the layer stack. I have to try approach from this video as well.

in ps the 3rd method i enjoyed the most. the image really came out great so i produced my first print. i think i will enlarge it over 3 gig file!!!

craig, my final image has more cyan in it and less red compared to yours, how could i fix this. excellent tutorial i might add.

gm craig, so i am at timeline-18:20, again i don't have to image solver because i did not do dynamic crop, correct??

craig, if my wpp was set for auto crop, why are am i doing another dynamic crop or do i skip that.

Outstanding! Thanks for the video.

Very nice lecture with one mistake, typical for advanced deep space imagers: You definitely can do astrophotography without a telescope! Depending on the target, a regular camera lens, even a wide angle lens, is sufficient to do serious astrophotography. Interestingly, images captured with wide angle lenses are used several times throughout the lecture. These images may not be as detailed as those captured with a telephoto lens or a telescope, but they are great to put the astronomical structures into a greater context. Many deep space imagers and advanced landscape astrophotographers use all the described techniques, like tracking, stacking, narrowband filters, and even cooled monochrome cameras in connection with regular camera lenses.

I learned something today! Thank you Craig!

very very informative Craig, really enjoyed this. one day i will have to step into the monochrome camera world. please continue your videos and thank you.

This was again a great tutorial Thanks Craig !

Great presentation for the student

That’s a great video Craig. I don’t really use photoshop in my processing except at the very end, and that is because I don’t know what to do. Seeing this has given me a good starting point. I have never really understood what all the blending modes do, is there a reference somewhere that you recommend that explains their function?

Thank you very much Craig for sharing your Photoshop process: very educational !

Thank you Craig for the great video. It was a good teaching point about plate solving, it was useful, not a problem.

Great video, thanks. I don't understand why Pixinsight takes so long to plate solve, and why, at times it completely fails. My Asiair can plate solve an image with a tiny computer in about 5 seconds, and when I used to use Siril could likewise get an image solution almost instantly. Pixinsight has been notoriously bad at doing this for quite some time!

Thanks for another excellent and very informative video. I always learn from your detailed explanations of processing in PI and PS. A thought on the Image Solving issue you had: I've used the Seti Astro PI script "Blind Solver" and it usually works when I've had otherwise unexplainable issues plate solving.

cool stuff Craig, I'll have to give this a try when I eventually go mono

Looks amazing! Thanks for sharing!

Wow So much changes with few things to do Great video great capturing its so clear unbelievable. My question is : are this data captured with mm camera or one shot color camera .

Thank you for the video. I couldn't really tell out what point do you do the main stretch? And how are you avoiding bloating the stars when you do the stretch? Are you doing a preliminary stretch? How do you keep the "exposure" of each panel the same? Thanks!

craig, much better results with your help, thanks

Thank you very much. A clear concise way of using these tools in a practical application. We have all watched you use these tools from time to time but you don’t always elaborate on them and today you did. This is a great reference video has a lot of your videos are great reference videos, thank you
