Here is the resulting image of M33 with the Svbony MK127+0.65x reducer on the SV605CC+SV226+UV/IR Cut camera, Cg5-GT mount, 30F4+T7M, SV192 heater. 91x60sec, Gain=130, Offset=20, T=0. Shot yesterday in Pushchino, Chuvashia. It was windy, with gusts up to 8-9m/s. 10 out of 100 frames were discarded, but the autoguider handled it.
When I started to disassemble the setup in the morning, I discovered that the guide scope was loose in its rings. Apparently, I didn't check it after the trip. As a result, the guide scope was slowly slipping all night, and this showed up as a slow drift in the frame sequences.
But overall, the telescope performed well. It shoots no worse than the C8-XLT, if not better. At the same time, the telescope is compact, lightweight, and has minimal wind profile, as demonstrated by the shooting in windy conditions.
