QHYCCD Standard Software Q&A / Re: QHY294C and temperature setting...
« on: February 21, 2021, 02:02:58 PM »
Power adapters that equipped with early QHY294C are too weak for camera cooler. You should use more powerful adapter(3A or more).

Mechanical Q&A / Re: QHY294M can't reach anounced temp delta

You can try to capture a 5 seconds frame, maybe the cooling effect will be better.

If you are not satisfied with the cooling effect, we can send you the replacement.

Best Regards
Nothing helps. 25 degree delta is maximum.
Should I contact local seller for replacement or you will send it directly to me?

Mechanical Q&A / QHY294M can't reach anounced temp delta
« on: January 31, 2021, 05:42:00 AM »
My new qhy294m cannot cool down less than 27 degrees below ambient. Is there way to improve temperature delta at least to -30? My old qhy294c can make -37 delta.
Thank you.

Here is single flat.
V0.1.51.41 ascom driver used. I have noted that capture stops with latest available camera driver and while using older driver it works better.
