My 10yr old currently uses a 4.5" F/4 Newtonian on a GSO SKyview Deluxe ALt/Az mount. Its pretty much the perfect scope for a child given adjustable eyepiece height, lightweight, etc other than one thing and that is aperture. I'd like to get a lightweight 6" newtonian for him that'll still work well on the GSO Skyview Deluxe (similar to a Porta 2 from Vixen).
I'd also like to keep the costs down as well
Anyone have any recommendations?
