M13
Taken with TMB 130/1200 with 0.6x reducer. The cluster was not well placed in the sky with a fair amount of light pollution in that area, despite that it turned out fairly well. The reducer turns an f9.23 scope into an f5.5 scope, which is considerably faster for imaging. There is distortion at the corners, but cropping took care of that. Stack of 116 frames in total.
