Greetings,
I am new to SGP and was using the Flats calibration wizard last night and was not sure what my full well ADU was for my Canon 500D was, but I think I might have found out but wanted to run this by this group for confirmation or correction.
I was doing flats for a few different ISOs and at the higher ISOs (800 and 1600) the first few 5s exposures all ended up at 62463 ADU - never higher. At 1600 the first two exposures were at this same number.
Is this telling me that 62463 is my full well ADU number?
Also, what is a good tolerance range for these flats? The wizard had no problem using its iterative process to get within 500 ADU at 400 ISO, but at the higher values it failed each time until I increased the tolerance to 3000. How far off 50% full well is too far?
Thanks
Tom
