Hello,
Is it normal for darks taken just one day apart from each other to have different mean and median ADU values of around 30ADU!?
First night, 10 minute (gain 200) darks were taken with a mean of around 913. Second night, the mean value was 939. A week ago, they were also different.
I'm taking the darks in a completely dark room, with AC on, using same laptop, software, power supply, cables etc...
Any ideas?
