Description

Whirlpool galaxy acquired with an Intes MN56 Mac Newtonian (5"). Normally a strictly visual scope, a 3X barlow was used to achieve focus readily. Also, the small secondary caused a very large fraction of the image with this camera to be vignetted. That together with the strong off-axis coma from the use of the barlow required a large crop to make this look presentable. Even still, the coma can be seen near the edges.

The RASA is still in the shop for repairs and the rare occurrence of a clear moonless night here in Oregon forced a desperate attempt at some imaging.
