just tossing this out there, GSO makes a pretty reasonable 2" eyepiece set. I have the 30mm, it's nothing spectacular but it's decent and costs about the same as the Orion Expanse. It's great for newcomers to astronomy - nice wide field and it's easy to get your eye in the right place. To be clear, this is something to perhaps consider *after *we get the Expanse set and/or modify the Blue Elsom focuser to accept 2" eyepieces. http://agenaastro.com/gso-2-superview-eyepiece-set.html
