Yep there is nothing wrong with DSLR's or OSC cameras. I used to use hypered film in the 1970's and a DSLR would have been far better, heaven in fact!
This is a twelve panel mosaic of a blend of NB and RGB done with my Canon 5DH and 300mm F2.8L lens at f/3.6. The camera was cooled to -12C. 20 MB

I did this some years ago. I was pleased at the time but longer or more subs would not improve the image much at all. I had hit the inherent signal to noise wall of the total system.
When Vela rises I will attempt to do the same mosaic with the new system. Here is a thread on just one panel.
