@michaellewis4732 4 года назад

Thank you for this post! I was able to dramatically improve an image that I previously attempted to process in PS. It was quite noisy and had a green cast from a narrowband filter that I couldn't totally remove without being overly aggressive. I don't have a lot of experience with PS, but I'm going to retry these techniques on previously captured images and see how much they improve.

Hi Aaron. This is a great tutorial! If I may add something. Balancing the colours as a very first step in Photoshop helped me to avoid strange colour casts, hard to remove at a later post-process stage.

Siril is a free astrophotography that is like pix insight in that it stacks and does a lot of post processing(the biggest being dbe) it removes gradients IMO a lot better. I would recommend it.

@stefanbalzer611 4 года назад

Hey, Aaron! Great Tutorial.Thanks for sharing! The tutorial again contains helpful tips. If I understand it correctly, you want to use the inverse star mask to prevent the stars from bloating when stretching. Unfortunately your approach is not quite correct, because the function "Adjustments-Curve" does not take the mask in the layer below into account. Only when you activate the button with the arrow down (left button at the bottom) in "Curve", the mask will show its effect. Otherwise "Adjustments-Curve" has an effect on the whole image. I hope I am not wrong with my statement. You are welcome to check it and tell me your result. Greetings Stefan

@AVAstronomy 4 года назад

Stefan Balzer thanks Stefan, now that you mention it I believe you’re correct on that. However, I’ve noticed that star masks tend get weird dark halos around them after being stretched. I’ve found that the arc sin stretches minimize star bloat even without a mask, but yes the curves should be done on the layer that is masked.

@PeeGeeTips 3 года назад

Forgive my confusion, but after watching this through I just don’t understand how the image doesn’t completely fall apart after using so many of the arcsinh passes, it’s like you could nearly infinitely keep doing it and reveal actual aliens in that image 😂 You’ve hardly any noise or image degradation yet reveal so many details within the nebula, what am I missing?

@AVAstronomy 3 года назад

Lol! For starters you have to have good data, Many dithered stacked frames(40 or so). There is a limit to the stretches. I usually only do about 3.

@clungebucket23 4 года назад

not quite at circa 5 mins,... one needs to clip the adjustment layers to the star mask to get the effect other wise you get global changes, but be careful with the adjustments as you'll end up with halos around the star mask holes.

@AVAstronomy 4 года назад

great point about the star halos.

@GMBaller3 3 года назад

Awesome tutorial. For the Arcsinh curves from Mark, in the cloudynights post he gives a process for blending them, using additional layers and the channel mixer. Wondering if you have tried doing that with the selective masking you've down here or if the two would be incompatible? I may try it myself, but I am pretty new to PS, so it will take me a while, and I am following your tutorial first, so thought I would as. Cheers.

@AVAstronomy 3 года назад

Thank you! I have tried his other method but didn’t really like the results I was getting. Other people do find it very useful though. I Astro Ed provides a really good tutorial on the method posted in cloudy nights forums if you want to give it a shot.

@NJ_Galactic Год назад

my dee sky stacker produces 32bit tif files, and when I import to photoshop it will not allow me to select color range. Should I change it to 16 bit in PS or is there a way to make DSS produce a 16 bit output?

@jameswoods1939 3 года назад

Amazing photo! Can you get similar images using a program like GIMP? I don't have a computer capable of running PS.

@AVAstronomy 3 года назад

Thank you! And as far as I know, yes, GIMP is a very capable editing software for astrophotography.

@ahmedfalih473 3 года назад

Very Nice tutorial.. I get stuck on the step when you turned the image into green background.. What keyboard shortcut did you use? is it alt + backspace? Thanks

@AVAstronomy 3 года назад

Ahmed Falih Thank you Ahmed! I think you’re referring to the light pollution removal technique correct? If that is the case then yes you press alternate backspace after you have color sampled the top layer color that you’re trying to remove from the picture.

@ahmedfalih473 3 года назад

Photoshop is overwhelming for people who don't use it much. I feel like I'd have a hard.time doing this

@AVAstronomy Год назад

I promise the learning curve is easier than pixinsight. There are other programs like Siril and Astropixel processor. But honestly all of them have a learning curve.

@sixbeerslater 2 года назад

Thank you for the video however It does not seem correct, if you compare all through the tutorial the stars actually do increase in how they are illuminated, even though you create the masks, this is because the adjustment layers you add have their own masks and masks do not stack between laters. This is pretty misleading and honestly adds a bunch of extra work to the workflow that does not actually affect the outcome. Don't get me wrong, I wish it would work as I have a Doublet and star bloat is a nightmare for me.
