Nice to hear you managed some eyepiece time with the new toy. If I may suggest, with my GSO dob I went and purchased a set of Bobs Knobs (from Bintel, cost about $100, get the full set, primary, secondary and springs) which makes collimation much easier than the standard GSO kit. Stronger springs hold collimation better and adjustments are tool free. BTW I am not plugging Bintel, thats just where I got mine!
Anyway, hope it continues well and we see LOTS of reports.
