The bad news is the stars were not as sharp as the focus was slightly off - my fault being in a hurry. The good news is Bill's Star reduction reduced the star problem quite a bit. The image is not great and I really did not spend a lot of time processing it since I did not have a lot of time on it, the light pollution was horrible in this direction, and the image was not the major focus of this project. The light pollution was so bad I could not make out any stars due to the light glow from Stamford and NYC. I was happy that I was getting something.
So how was I able to even find this given the sky conditions? Using the ASIAIR for Plate-solving. Plate-Solving is standard procedure for using go to mounts, it is less commonly used with tracking mounts such as the iOptron SkyGuider Pro which I was using. It actually worked quite well especially since Jacek Witkowski lent an extra set of hands (Thanks). I could have chosen an easier object that was actually visible to do this test with but I was at the offsite cemetery again and wanted to do something that is not visible very long from my yard.
