Yep definitely keep on with it Steve, that's a good image. The C11 has a lovely image scale, should pull some of the outer halo with calibration I reckon, I think theres some there to be teased out.

Looking good steve, huge scale as Phil says, what kind of focal length does it run at normally and what is it at with the reducer?

f10  so nearly 2.8m native

 

somewhere between 1500 and 1700 mm Eddy I have a bit bigger gap between the reducer and the ccd than for 6.3 reduction so I guess 1600mm maybe about the mark
