I have a focusing issue that I am struggling to understand. I currently use an ASI294 and ASI183 on a C11(CS) with Hyperstar. The 294 performs great and autofocus (SGP) focuses down to 2.0 and less with great quality. When I mount the 183, I cannot get the HFR below 4.5 and autofocus cannot come up with any better result. As a test, I borrowed a friend's 183 and attempted focus. I got exactly the same result.
Perhaps someone can give me an idea on a direction to solve the problem.
Does the camera profile in SGP actually show the 183s correct sensor size and pixel dimension or did it do an auto copy of the 294s data over into that profile?

Thanks for your responses. I have the 294 and my 1st profile and the 183 as my second. I should be using the second profile for the 183. Yes, I did change all the data to reflect the 183.
