My scope is an Orion Optics UK AG12.
It’s a fully corrected 12 inch f3.8 Newtonian Astrograph, mounted on a G41 with Gemini computer control.
I use a Starlight Xpress SXV-H35 and FLI Focuser to acquire the data with the optional Starlight Xpress guide head, and an off axis guider to keep it where it needs to be while imaging.
For the observatory I decided on a roll off roof design. Although the scope is open to the elements the air temperature equalises very quickly keeping the seeing as good as I can get from my location.
