Imaging Processing Fun with M51 Whirlpool Galaxy

M51

What happens when you spend 3 hours imaging an object only to find that you have only a handful of salvageable images from the session?  That happened to me back on May 3rd when I imaged the Whirlpool Galaxy.  During the night, at some point, I lost guiding and did not catch it so when I went to process the photos I was surprised to see that 2/3 of them were unusable.  Having only 13 images to work with, I processed the images 4 times over to see if I could get a decent image to come out.  Along the way, I learned a ton (as usual).  Here are some of the things I tried and the outcome of each method:

1.  RGB Misaligned – MaximDL RGB Color Combine (Average Method) + LRGB Combining in Photoshop CS6

The image above is a result of the RGB images being misaligned when processing.  Sometimes I get a little impatient and don’t take my time getting everything perfect during the post processing aspect of Astrophotography and this can result in very sloppy images.  When the RGB channels don’t line up, you get a mess of colors scattered throughout the image.  The RGB and the L images were first combined (using the Average method) in MaximDL and then combined in Photoshop CS6.  As you can see, even Photoshop can’t save this image.

2.  LRGB Combination in Photoshop CS6
