I was trying the QHY5 in the SHG set-up - hoping the pixel size would help with a vertical interference pattern I seemed to be getting with the ASI 174.
Using Firecapture (I usually get around 60fps with the ASI 174) but the QHY seemed "stuck" at 4 fps. Changing the target frame rate, buffer etc etc didn't make any difference.
Changed to SharpCap but got the same results, still 4 fps.
Any ideas from other users???
