Good info Peter, you've been busy! Interesting that temp has no effect. Now to try and interpret the data......and then ask numerous irritating newbie questions
I presume the exposures were done with a constant value of illumination from your light box, so with that fixed level of light, anything beyond about 7 seconds will start to cause white compression? How does this affect your choice of flats exposure time, and in your opinion, how does it relate to other amounts of light (eg; night sky objects as we see them?)
What gain and offset do you use on the QHY8Pro?
I'm not sure what point I'm trying to make, just asking the questions that come into my head
Cheers,
