Front to rear: Halpha filter solar telescope, 4" Newtonian (setting flat on spare pier--I use that scope mostly for photo--makes a good 1000mm f10 telephoto lens--I was the only one in Africa that got bird pictures--a good bird picture requires you get the eye of the bird), 4" Newtonian (silver on short tripod), 5 inch refractor, and a few binoculars. I have more binos in various cars. The Newtonians (Newts) are reflectors, that is they use ground mirrors rather than ground lenses, one flat one concave; the refractor uses refracted light, light bent by conventional lens. Each has it advantages, but all large scopes are reflectors.
