Description

My longest integration time I have ever done on a single object. I used a slight different Pixel Math Expression Artūras Medvedevas posted on his website for the combination of HA and OIII.

Post processing was done in PixInsight and Photoshop. Total integration of all frames are about 25 hours (243 HA frames & 255 OIII frames).

Please give me some feedback, I want to improve.
