Description

My M42 and Running Man for 2022/23. I normally use one sub-exposure time for images, but I decided to experiment and combine different times. Not sure if that made a difference but I do like the result. I also used some of the features of the developer version of Siril including the improved deconvolution.

Pixel math for Siril:

R: Ha
G: ((OIII*Ha) ^ ~ (OIII*Ha))*Ha + ~ ((OIII*Ha) ^ ~ (OIII*Ha))*OIII
B: OIII
