For comparision I have posted a 180 second shot made with my 300D + 50mm lens to compare with Berts 5D + 85mm lens (similiar field of view). To be fair on the 300D
the shot was made at 3x slower optical speed (f3.5 vs f2) and in 26 C ambient versus 12 C (according to BOM records). Its possible I was using the Peltier cooler so equivalent temperature would have then been ~20C. When it is clear again I'll do a 10sec 50mm f2.0 shot of Orion with the 300D to get a better comparision. However, it is clear there have been some major improvements in noise and sensitivity!
