Finally again some clear nights… with the observatory nearing completion, I could focus a bit more on actual imaging and fine tuning the optical setup.
The GM1000 mount carries the 180mm F/15 Maksutov, and with a Astropysics CCDT67 reducer, I’m experimenting to image @ F12 with an APS 2600MC camera. The focuser is an Esatto 2″.
