Managed to get my 5D on top of my 80mm.
On the pic with orion at the bottom left, that tiny clump of red to rightish center of the picture, is that the flame nebula?
All three shots are with the 135/2 at around f/3.5 from memory, at 1600 or 3200 iso for 30secs - not up to stacking yet! I gave the 35/1.4 a try briefly but it is too wide for where I have the camera, the scope was getting in the shot! I didn't bother doing any dark frame subtraction as the 5D is pretty decent at 30secs.
I'm picking up the remote to do bulb exposures tomorrow, so expect the clouds to come rolling in.
cheers
