I recently switched from a trusty ST-10XE to a ST-10XME to leverage that model's greater light
sensitivity as a tool to better manage my local light pollution. I've always considered M101
kinda cool and since it was well placed after midnight, it became my guinea pig. Unfortunately,
I had to cut my planned exposure time due to our delightful winter weather and therefore was
forced to deal with some noise and apply smoothing- hopefully enough but not too much...
