Description

I was all set to make the most of a clear, moonless night, and after shooting M100/Ceres, I switched to the Takahashi FSQ106 scope for Markarian's Chain. Unfortunately, the temperature dropped and that Takahashi 's focus is VERY sensitive to temperature changes. I had to dump 40/100 frames and lean heavily on Russell Croman tools for noise and detail.
