Reprocess of M45: slight improvement

[michael.h.f.wilkinson]

Restacking with sigma clipping did improve the result in that the satellite trails in the original posted earlier here:

Version 1:

Version with saturation boosted a little:

Still thinking I should try to control the noise more. I got some more darks this evening (it was cold enough for that, but too hazy for imaging). Restacking with better darks could reduce the noise a bit, and then I intend to try some (gentle) noise reduction, followed by contrast stretching of the nebulosity, and then perhaps do an increase of saturation only in the high luminance area, to avoid boosting colour noise in the background.

At that point in time, it was.

Wonderful deep image - I did not realise that the clouds were so extensive in that region.  Well done and thanks for sharing your latest version.
