7th December 2023: added payment option Alipay to purchase Astro Pixel Processor from China, Hong Kong, Macau, Taiwan, Korea, Japan and other countries where Alipay is used.
Taken with the FLI Kepler KL4040 at the Oregon Star Party July31-Aug2. 65 3-minute subs each Ha and O3. 16 darks, flats and biases. My first "serious" image with this camera under dark skies. This camera is highly sensitive but difficult to calibrate - Vincent was a GREAT help in getting an acceptable result!
Thanks, but it's your data so well done! Maybe, if I may, the background is a bit too dark and you used some de-noise tool I think which hurts the finer details in the nebula.
Thanks Vincent, god points. I tend to over-process. I'm redoing it to go to a grey background with a lighter smoothing touch and not much other processing. I'm also running a larger set of darks and biases (50 each) to improve calibration. Will post update later

I share Vincent's argument, I think the background is a bit too dark and possibly clipped.. I prefer to process not so dark, if you do, fine details get lost very easily 😉
OK I ran some more darks and reprocessed from beginning. Combined in APP - looked at lots of LRGB settings, ended up R=Ha, Green = 25% Ha 75% O3 and Blue = O3. Very light touch on denoise (using Topaz AI) and set background to about 35 (scale of 0-255 photoshop levels). Hope it looks OK on the web and in jpg format
