Description

M109 taken with my Vixen R200SS and focal extender from f/4 to f/7.5. This results in 1500mm focal length. I wanted to give it a try for the tiny galaxies. However, I had to crop two thirds of the image, because the stars are distorted towards the edge of the frame. Not really a great option ...
