Just looked at the ZWO graphs, and yes a gain of 100 is very good in all respects and I wish QHY did that; and it appears a single readout mode too.
Notwithstanding, how can they recommend a gain of 0? Just what sort of SNR would you achieve with that?
Also, very happy to see dark current of far less than 1 e/pix/sec.
When I have been collimating my RASA using sharpcap and 1 second exposures, I have turned the gain down to something like 35 and the star has become extremely faint.
Clearly, ZWO’s implementation of this sensor differs significantly from QHY’s
