This is my very first image posted on AB 🥳. Though I have worked on astro-imaging for more than 1 year but I have been super unproductive due to my lack of time(I'm a student). In my opinion this is my best image. It map Sii to red color, half Oiii & half Ha to green, and Oiii to blue. I use 30% SCNR degrees to make this image looks like Hubble palette.

A side note from the technical info, I'm super grateful with this image. The process of producing it helped me learned few more Pixinsight techniques and taught me about the narrowband processing. More and better image coming soon 😉

BTW if anyone could leave some feedbacks for me in the comment, that will be very helpful. Wish to learn from you all!
