That was two votes for a Dobsonian-type (thanks Eric Hahl and Pazuzu). Although I saw conflicting information in my searching, is the
primary difference in a Dobsonian and Newtonian type system simply in the type of base? I discussed this possible Christmas present for me with my wife last night and she was thrilled!!! (I think I might know what I am getting for Christmas). Following the advice here, I found a new candidate and the additional aperture afforded by a 6" scope pays huge dividends! -
