Description

I went a little overboard with this project this summer.  I wanted to see what I could do using multiple exposure times and combine them with the HDRComposition process in PixInsight.  I did five different LRGB exposure times (L=15sec, 30sec, 60sec, 120sec and 240sec; RGB = 22sec, 45sec, 90sec, 180sec and 360sec).   I think this was a classic example of the "Juice is not worth the squeeze" as I'm not sure I really made any dramatic improvements in what others have been able to accomplish with similar total integration times and good processing techniques.  I'm sure I'll try M31 again doing something else.  M32 and M110 are some kind of mess in this image, so please forgive that.  It was an experiment.
