Description

My first night in over two months and the wind was blowing like crazy. The plan was to image NGC5033, but it made no sense to set up the big 8" newton. So I used the little 5" to observe and the Omegon MiniTrack LX3 to image the Rosette region with the 85mm.

While I made a few tests with the LX3, I let the baby newton run on M101, unguided and with manual polar alignment only. I used my car as a windbreak as much as possible and was really surprised how well that turned out. Another kind of lucky imaging😄
