Really excellent results John - well done:-) Your M27 looks about the same image scale as my M27 via 12'' @ f/3.6 and 1100mm fl - could you be working at f/6.3 rather than f/ 3.3?
The new CN3.0 must still be transitioning images, all of em are not showing up :-(
However, I'm certain I have the 3.3 reducer in place and no cropping/zooming was done. The LSx2 gets right up to it FR, I wonder if that is increasing the image scale that we are seeing? This means that I'm not at f3.3, the closer I get to the FR?
