Hi Andrew,
Thanks for posting your results. You have the same camera as me, so it is interesting to see your results.
It is a while since I ran my test, and I don’t think I removed the hot pixels, so it is possible they are the cause of what I saw. I really wanted to measure the median pixel value, but the software I was using did not calculate that statistic. So I measured the max, min and average pixel values. Leaving the camera be, and then running a series of bias and dark frames. I must redo it sometime, this time removing the hot pixels.
Here are my results for reference.
Test Run 1
Test Run 2
Cheers,
Andy
