My main object during a small series of clear nights was the Crab Nebula, Messier 1. On each of the three evenings, I was able to capture a star cluster preceding the Crab Nebula.
In the meantime, I had to (successfully) adjust the VC200L, eliminate backlash on the mount (successfully), fine-tune the Off Axis Guider (successfully), and 3D print a new adapter (successfully). Unfortunately, the existing adapter was too loose in the frigid temperatures, dropping as low as -6°C.
