G3M662M

Nice build quality, excellent sensor and reliable and capable software for adjusting image properties before sun, moon and planet capture. Very quick and easy to set up and everything runs without any issues. Great value for money.

After I stalling it on a 30mm scope and downloading the proper ASCOM drivers, I had no trouble operating the camera. It works fine in NINA, PHD2, and Sharpcap. No comms issues either. I did purchase a heavy USB cable for computer connection.

Tested it out and I'm pleased with its HDR function and very sensitive sensor, I'm using it as a guider in IR currently due to its small fov and faster data rates because it's 1080p

This is a real vfm product. It's the perfect cam for subs under 1s which will help you guide your harmonic drive at optimal performance.

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.
