Description

I Finally had First Light with my new setup last night. The telescope was recently upgraded, the 400mm F/4 mirror stayed, a new KAF16200 camera with 7 filter positions, a new 3 inch comacorrector, a 3 inch focuser and a much bigger 120mm minor axis secondary .

The 10Micron GM2000 QCI was replaced by a Mesumount 200 Mk2, which has less problems with the heavy telescope (some 50kg), and it tracks like a dream!

600s integrations, one each for LRGB, acquired from my backyard. Collimation is still a bit off, but I'm getting there. As soon as the telescope is working as it should, it will move back to my remote observatory in Germany.
