This is the result of last night 3hr of OSC data with an Optolong L-eNhance filter (40x300sec)
. Stacking/extracting Ha & OIII with APP, post processing with Photoshop. Please let me know what you think and what to improve. Still need to find a solid Photoshop workflow to get better results.
IMO I would remove the Green from the background using "9) Tools" (HSL Selective colour). 0 - Background, G<-> +50%, SAT % -50%. its from a tutorial I saw a while back. I now do this on everything, brings a real nice charchoal grey background.
One thing I did learn. I always try to get everything right before stretching my image. After that its in Photoahop, Denoise AI, vibrance and such and final Sharpen AI (from topaz).
How did you extract "HA and OIII in APP" and for what purpose? Very curious to see how and why you did that :).
@michelaudette hi Michel,
thanks for the feedback! I never use the hsl tool in APP, I think this tool is too complicated. But I’ll try it next time! Which tutorial was that?
I extract in APP via tab ‘0’, below the debayer setting there is a dropdown where you can select Ha/OIII - Extract Ha. You end up with a Ha file (and OIII if you do that as well). Then I use photoshop to combine these 3. This was the first time I used PS for this btw. Before i used the rgb combine tool, but i couldn’t ever get the balance right in there.
Thanks so much for the tip. I am definitely going to give it a try. so ASI2600 colour camera with a quad narrow band filter. Then you debayer use this tool you proposed.
Yes, to combine Narrow band (Which I did in Mono) I use Pixelmath in Pixinsight. you can spend hours finetuning it :).
Love your image - I just shot almost the same thing in RGB (My narrowband filters are being put into new cells) You image has a lot of good detail!
My questions is, how did you add the little about box on the bottom. I really like that and have seen it on other folks images but am not sure how people are doing that.
I did redo it a couple of times with the same data, but different post processing. I’ll attach the final image (for now with this data).
I made the ‘about’ box in Photoshop. Just added a new layer with the text, a black box and signature. The black box I lowered the opacity to make it see through. Hope this helps.
Seems simple enough, thanks!
