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 ETX-105 is a portable and potent scope, capable of some modest deep space observing without being difficult to carry.
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.
