Thanks guys, you have been all really helpful. The 10" or 12" Dobsonion definitely sound like what I'm looking for. I'll looking into getting a look through one before I order though.
Been just comparing the prices between ozscopes.com.au and bintelshop.com.au, and there is 3 kinds of Dobsonions(standard, not collapsible) - Saxon, Skywatcher and Bintel. Both the Saxon and Skywatcher have the same "specs" and all 3 look the same except for a branding sticker and the stand. So is there any advantages between the 3 brands?
