I am interested in the QHY247C. How does it compare to the ZWO ASI071?

Hello,

          I think the most advantage is of QHY247C is the thermal noise control of our camera. You may compare with QHY168C and ASI071 20 minutes dark frame:

          And the QHY247C has similar / a little better dark noise control than the QHY168C.



          For other parameters. QHY247C has lower readout noise.
