Fred,
I can't believe the PE trained result myself - but I can't see where I stuffed up the procedure. I'll re-run it later and see if results are consistent, I would be delighted with +/- 5 arc seconds, 2 seems way too good to be true. PEMPro reported ridiculously low PE - I'm keen to test this once the skies clear! Perhaps my image scales was out - but it was PEMpro that calculated it by looking at sky trails on a snap with the mount paused for 10 seconds.
The two shots in the first post are a 10 and a 16 minute unguided snaps - stars are slightly elongated meaning there was some PE or a bit of DEC drift.
Frankly I am dying to get the scope properly 3 stage colliminated - I guess its basically at stage 1 collimination, I'd love to see what can be achieved when the gear is all working together well.
Fred - it my shots were even half as good as yours I'd swoon! In a few years maybe I'll be close. I'd love to see what I could do with a serious S-BIG camera - many moons away for now!
