Man o man Geoff, you'd better get a band aid. That's a nasty graze there. Too cool
Well I'll just have to overwhelm you with quantity then. First shot, (top one) prime focus with a 2X barlow, about f/20.
This one prime focus again, with a barlow but attached to a meade variable tele-extender. I'll work out the f ration and focal lenght tomorrow/nearly today and post them later
