I just bought my first telescope, finally settled on the Orion XT8 after originally considering a Celestron 90EQ refractor or 130EQ Newtonian. Figured I might as well get something that will last me a while from the get-go instead of wasting money on lower end scopes. Anyway, what are some good eyepieces to consider getting? I believe the XT8 only comes with one 25 mm piece, so I think I'd like to get a 6-10mm piece for planetary viewing. Also, should I get one of those laser collimators, or will I be able to get by without one?
