For those wishing to create their own a la carte system for observing, Meade offers the optical tube assemblies of their fine Schmidt-Cassegrain telescopes.
The LXD75 Schmidt-Newtonian configuration is a large and potent scope, capable of some serious deep space observing of nebulae and the like. The Schmidt-Newtonian design, because of its special corrector plate, is quite superior to the standard style Newtonian reflector telescope. The sharpness of the field off-center is comparatively stellar.
All of the Meade optical tube assemblies are offered exclusively with their UHTC Ultra-High Transmission Coatings, which increase the effectiveness of any telescope aperture-for-aperture without adding to the weight of the rig.
