G3M662M

I took the 662M as complement to the ATR585M. It is now in use as guide cam. What can I say, I had no issues with it whatsoever. It works perfectly both in SharpCap and PHD2. Sensitivity is very good and frame latency is small. Well suitable for 0.5sec guiding for my harmonic drive mount. Works in Metaguide as well, but i only tried it for a bit. I also have QHY678M and picked this Touptek camera, because the QHY678M appear to have certain delay/latency after the frame capture. What I absolutely love about the both Touptek cameras is that when i change the exposure time in SharpCap, it resets the exposure right away. This was not the case of QHY and if there was for example 30sec exposure going on, that still needed to be finished before new frame with shorter exposure came out of the camera.
