First of all, it's HARD to collect S-II and O-III data in the backyard!12 hours of O-III and 12 hours of S-II data added to the previous HaRGB combination. No doubt that I didn't collect enough. Checking back the HaRGB, the sharpness of the details was not there either. I could blame the bad weather and entry-level equipments.
I do need a good mount to boost my courage on collecting data. The result is not that optimal. Only surprise is that the S-II signal added the touch of golden edges here and there. Tried to do the pure narrowband tone mapping and failed miserably.
This time I tried something different - I did most of the processing in non-linear state. This includes background level, de-noise in Photoshop and star removal in Straton.
Whatever it is, I will do this target again in the future when I find the "perfect" mount.Pre-processing of Ha Master- Calibration / Integration, Astro Pixel Processor
