The sky cooperated for a little while tonight so I was able to do some imaging. I did not
take as many light frames as I wanted because clouds moved in and pretty much covered the
sky. However I did get an image and I'm pleased with that. I decided to image M109 because
it's been about two years since I last imaged it. With all of that said this is my most recent
attempt at imaging M109. Please enjoy.
