hehehe we actually have been saying Newt all along just in the form of Dobsonian.
there are a few main types of telescopes
Newtonian/Reflector/Dobsonian - Mirror at the back
Refractor - Lens at the front
SCT - Schmitt Cassigrain Telescope - Lens at the front Mirror at the back
if your getting your hubby a 700mm newt we would be green

because that is massive something like 2 ft mirror
but a dobsonian around the 6" mark is nice or a 150mm Newt for 350 is just as nice a few extra bits to fiddle with but all good at the end of the day!
