The adage "bigger is better" may not always apply, but in the case of telescopes, with other things being equal, it is definitely true. The bigger the telescope, the more light can be gathered, and the brighter the final image. A bigger telescope requires a correspondingly larger mount/tripod to keep it steady. The result can be quite an imposing instrument. A few companies at the show have scopes (PlaneWave, Meade) and mounts (Mathis Instruments, Astro Physics) for researchers and enthusiasts with seriously DEEP pockets. These are not the kind of scopes one would bring into the house after a night of looking at the stars, but the kind one builds a house around.
