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.

Cheers,

Michel

Hi Michel;

 

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).

Hi,me again...

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. 
cheers!

Michel

Hi!

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 :).
