Excellent report ZeroID, sounds like you had a great time!
Just a word of caution on the change from 4.5" to 10". As a person who normally views through a 4.5" but regularly looks through bigger scopes at club nights and star parties, I'd say that the difference in views are not as "chalk-&-cheese" as Patrick and the others would say. Sometimes the expectation that a whole new world will be revealed to your eyes leads to disappointment.
The principal differences will be firstly that your current eyepieces will show objects slightly larger than you're used to seeing because of the increased focal length. Familiar objects will still look familiar, but a little brighter, with some more stars showing. You'll be able to increase magnification on faint objects without them disappearing! And you'll be able to see some faint objects that weren't reachable before.
For experienced observers like Patrick who have incrementally moved up in aperture and who are used to teasing the maximum detail out of faint fuzzies, the differences are real and do seem like chalk-&-cheese. But it can be a bit like the wine buff who tells you that there are massive differences between two Cab Savs, when they both taste like plonk to you!
That said, it's a great step-up and the 10" will serve you well! Good luck with it all!
Cheers -
