Hi All,
I have a new QHY183M and using this camera for the first time, I have taken 20 dark frames using Sharpcap pro using the capture darks option at unity gain cooled at -5 and -10 degrees at 60 seconds to create 2 master dark frames. The image when stretched shows a lot of speckles.
My questions are, is this normal for a CMOS and this particular camera? Are there an unusually large amount of hot pixels?
I'd appreciate it if someone could look at them and let me know if this is normal for darks for a sensor like this or whether my sensor has issues. Images are attached. Thank you.
