so, for best resolving power, the objective lens of a telescope needs to be as large as possible, and have the fewest optical elements. for portability, the physical size and weight of the system needs to be as small as possible. within these two disparate parameters, what do you consider the best compromise for a portable telescope setup? a 6 or 8" newtonian is affordable, and quite a capable instrument in good seeing conditions, but no where the equal of larger 10-14" scopes, and even a 6" newtonian is quite cumbersome to lug around and setup. a dobsonian mount is simpler but quite limiting for anything but simple viewing. refractors can be pretty compact and yeild nice imagery if you can live with short focal lengths, and spend many money for nice quality. folded optical systems offer long focal lengths in a compact system, but are expensive. a 5" cassegrain is fairly portable, but 5" is pretty minimal for quality resolution. an 8" cassegrain is quite large and heavy, though fairly common amongst avid amateurs in the field. so - what do you suggest for a general viewing instrument, capable of good planetary viewing as well as medium wide field viewing, capable of long exposure astro-photography, yet still portable and easy to set up for one person? thanks for any thoughts.
