DSLR Imaging and Darks
For those who use DSLRs for imaging at prime focus has anyone done a comparison between using the cameras internal long exposure noise reduction and conventional dark frames
When I first started AP 3 years ago that’s how I use to image it but added double the capture time , so decided to capture conventional darks with advice from members
I would assume that the internal darks are matched more closely to the subs characteristics and therefore reduce noise and improve SNR to that of conventional dark calibration frames
I welcome and comments or advice on the above topic
