Nice start Marc.

Did you stop down the lens a bit? Most camera lenses work best when
stopped down a few stops as they are not as accurate as telescope lenses and zooms are less accurate than fixed focal length camera lenses as well. The zoom mechanisms enters an optical compromise.

You'll get less coma as well if you stop the lens down.

But at the end of the day nothing beats a nice dark site so this is a good result from taking it from your light polluted backyard.

Greg.
