My first ever narrowband image using PixInsight and my new CMOS Camera.
Since I‘m fairly new to Astrophotography, I had lots of problems while imaging, stars got elongated and blurry (like 3 hours in total were scrapped)

Post processing on the hand was really fun, I could work out lots of details in Photoshop, since I‘m still learning to master a good PixInsight workflow.

Total integration of all frames was 12.9 hours (129 HA frames & 129 OIII frames). Final image is an HOO combination.

Please give me some feedback or better workflows I could apply, I want to improve.
