Thanks for replying John
I should have (added) mentioned exposures typically from say 2 minutes to 5 minutes plus where dark current , read noise and shot noise is a real big problem for DSLR’s
At relatively short exposures noise is fairly easy to control with conventional darks, dithering and multiple exposures
