hey merlin,
I still think in magnifications, so for my 1250fl 10" newt, are you interested in basically if i take an image at 1250 x 5 (5xpowermate) and then at 1250 x 2.4 (2.4 x barlow).
I can get some extension with the powermate to 7.7x if i have the ccd 10cm away from the powermate, so i will test that as well. I mean to make an extension tube to see if i can go any larger.
