A Bird-Jones (or Jones-Bird, depending on who you talk to) Telescope (aka Bird-Jones Newtonian, Bird-Jones Reflector, Jones-Bird), is a derivative of the Newtonian telescope design. A true Newtonian has a primary mirror with a parabolic curvature, and a flat, angled secondary mirror. A Bird-Jones telescope uses a primary mirror with a spherical ... http://darksitefinder.com/maps/world.html
WebA Bird/Jones Newtonian Reflector is a modified Newtonian with a spherical primary mirror. Before the light strikes the flat after being reflected, it passes through a Barlow-like achromatic lens that corrects the spherical aberration of the primary mirror.
