Sensor Analysis setup for QHY168C
Posted: Mon May 30, 2022 6:29 am
Hi Robin,
I successfully got the sensor analysis to complete, but took about 10times trying different capture areas (the red box) and brightness. After I did get it to run, I found it very compelling and powerful that you (anybody) can create the programming to go through the myriad of camera adjustments and measurements. Then add to it 50+ different cameras models/brands it can work with. Wow! Only John Murphy's NSG script has given me that feeling before.
-- Does it matter if Debayer preview is On or Off?
-- Does setting the Resolution in Capture Format and Area have any affect? Smaller areas let the camera get more FPS. I left it at my cameras max resolution, but maybe smaller would be better.
-- The adjustable red framing window on the sensor analysis screen is what I adjusted to finally get the analysis to complete. Is there any way to know the framing size in X - Y pixels so I can go back to it easily in the future?
-- My Camera Controls area shows R, G and B gains. SharpCap takes over these during sensor analysis, so my setting them does not matter. Does the separate Image Control Gain have any affect on sensor analysis? I set it to minimum.
-- My camera also has an offset. SharpCap takes over that during sensor analysis. Is the Smart Histogram going to tell me the recommended offset?
-- My sensor analysis results were pretty close to the QHY spec sheet. Good to know. In SharpCap's sensor analysis output chart the first column is called Gain. Is this actually my camera's Gain Setting, and is it the R, G and B adjustable gain setting in Camera Controls?
-- I doubt my, or any, color camera has equal sensitivity (efficiency) in R, G and B. If my light source was not white, but tinted or even predominantly in one color will that affect the sensor analysis? Haha, I should just run it again with different color films on top my light panel. But please comment.
Many thanks, and I will be upgrading to Pro soon.
