I have started to be under the impression that you just can't get a "good" image with a dslr (and many others are too) , because it's uncooled and has massive amounts of noise and relatively low QE.
Would you say this is true? Honestly while imaging and processing my data i have found this to be true. I think i would need to get thousands of frames just to get rid of this noise!
Or would imagine at a faster f ratio help to get more data? (when at a dark site)
