Description

This is a reprocessing of my first LRGB image with my ASI1600MM-C. This was taken over four nights with separate FLAT by filter each night. I used a gain of 76, offset of 40 and USB of 60 with the temperature of -15C.

71 X 120s RED

69 X 120s GREEN

59 X 120s BLUE

69 X 90s LUM

41 X 240s LUM

All the frames were stacked with PixInsight and had much better star regestration both for each filter than Images Plus with better matching and aligning the different filter master light frames. The 90s and 240s LUM channels were combined with HDR in Photoshop for a Master LUM. This was done prior to learning how to use much of PixInsight.

The R, G, and B data was combined in Photoshop as an RGB image. All the gradient removal and Inverse ArcSinh stretch was also done in Pixinsight.

Final sharpening and curves adjustments were done in Photoshop.
