The ASI version has its issues with adapters as well. I read a lot of posts about both. Most seem to think the existing opening on the ASI6200 produces vignetting and it too small. Also the tilt plate is no good. I have an ASI183mm Pro which is a nice camera and has been good to use so far.
The QHY dovetails is 77mm and the FLI filter wheel opening is 74.4mm so that is close but no cigar so it looks like I bolt a dovetail to the "tilt adapter" of the qhy600 on the filter wheel side and on the camera side it goes to a male M54 thread to screw into the threaded opening.
I use my high end FLI CFW 5/7 filter wheel with 50mm square 5nm Astrodons on many cameras including the ASI183. No problem.
What problems have you heard of specifically with CMOS cameras? I will be running the camera separately from other devices on its USB3 cable ( a better one than supplied).
There are several things that made me decide on the QHY600 over the ASI6200 (both seem good cameras so its not a total one sided win).
QHY offers the industrial grade sensor, ASI the consumer grade. This is very similar to the old Class 2 and Class 1 CCD sensors.
The consumer grade has a plastic housing around the sensor the industrial a ceramic. The industrial grade has less hot pixels. Its designed to last longer.
The QHY has these extra read modes that offer various advantages. ASI though would be simpler.
ASI6200 thread recently about microlens reflections on narrowband images with bright stars recently was concerning.
QHY fix for the horizontal banding is a good plus.
QHY has a much larger 1gb of DDR3 versus 256K in the ASI.
The ASI has a 2 USB hub which would be useful to reduce cables.
But more importantly the best images I have seen so far from the IMX455 are almost always QHY600m. At the end of the day I judge by results.
But as I say I think both cameras are very good and anybody would be happy with either of them but the above points were important to me and the extra cost is worth it.
