M45 R CP STR


M45 R CP STR

This is the RED master from my LRGB image of M45 with my ASI1600MM-C. I used a gain of 76, offset of 40 and USB of 60 with the temperature of -15C.
This was 71 X 120s RED filter frames.

There is little evidence of the radial artifacts from the interference/diffratation/reflection ring patterns seen in the NB images, but there are substantial halos around the brighter stars
