I was able to get out and get a few hours of M31 data. After getting used to my ES127 and Esprit 100 I found it very difficult to focus with the DSLR lens. But it was my only option for capturing M31 other than doing a mosaic.
I'm a little disappointed in the detail and color balance. I want to try again but I'm not sure when I'll get a chance. CC welcome!
