I have been experimenting with OSC (QHY8) and modded 1100D, my personal comments are:
1. DSLR easy to operate, cheaper to buy and mod and BYE is fool proof to operate. On the down side, 14 bit v 16 of a OSC, sensitive to ambient air temp.
2. OSC can be cooled (regulated in all new models now, unregulated in my old QHY8), 16 bit sensor. Capture programs like Maxim DL and Image Plus take a bit of learning, but not too difficult. They can also stack which is a plus.
The biggest difference in my view is the pixel size, the 1100D is 5.17 and the QHY8 is 7.8, makes a huge difference to sensitivity and also allow me to using longer FL scopes (eventually
).
My 2 cents.
