Description

M45 taken at ISO800 56 x 150 subs as comparison with same (previous) target taken with 8 x 480 sec subs at ISO200.

For the B version I decided to go crazy with the stretch and contrast adjustments to see what was lurking in the background. Now I have to work work out how better to control it....

Version C uses a Gaussian blurred invert luminance mask to extract the fainter nebulosity from the background without totally blowing out the bright stars
