Sensor analysis Asi1600mc Pro

Post by Starman » Fri May 11, 2018 6:26 pm

I ran the sensor analysis using natural light several times with basically the same results, but not sure if I am doing something wrong. The steps it took in measuring the gain just doesn’t seem right to me. My camera gain is 0-600. Yet in the analysis it only went up to 500 and also in it steps of measuring gain values u can see it went from 0 to 60 to 61 gain and so on... any thoughts on if this is correct or did something mess up? Any feedback would be much appreciated.

Thx Paul

it's meant to work that way. The top of the gain measurements are limited to 500 because the maximum gain of 600 is very difficult to measure correctly and useless for deep sky imaging anyway.

The 60/61 is to try to spot if the camera changes mode at that gain level (some ZWO cameras that have Low/High conversion gain settings do). I think some change at 120 too, so I really ought to make it measure at 120 and 121 too. The 1600 sensor does not have the mode change at 60 gain, so you get two points close together - for sensors that do change more the value at gain=61 would have a substantially lower read noise.

Thanks for clarifying that Robin. I’m happy to know it wasn’t an error on my part and the program worked as intended. Sharpcap is a fantastic and I really like the new features. Keep up the great work!
