New Camera Information / QHY268C No Threads on Front Dovetail
« on: February 19, 2021, 08:49:01 AM »
Hello everyone,

I recently purchased a QHY268C-PH and have run into an issue. I expected there to be M48 threads on the front dovetail of the camera as there are on many other QHY cameras, and as there is on the front plate of the ZWO ASI2600MC Pro; however, this is not the case. Because these threads are not present, I must use the CAA, and no longer have enough back focus for specific configurations, which is extremely unfortunate.

Is there something I can do to fix this? The QHY268C manual makes it seem as if there should be threads on the front of the dovetail such that it can be used without the CAA to have a back focal distance of 17.5mm, but this is not the case to my knowledge.

Is their a way to get the full 17.5mm of back focus with the QHY268C-PH?

Thanks,
Ben
