In terms of what you can see, bigger telescopes are better. But bigger scopes also require bulkier, heavier mounts to keep them stable, and consequently, an equally brawny owner to lug them around. Enter the Apex 127. It boasts big 127mm-diameter (5-inch) optics but in a tube that's a fraction of the length and weight of a Newtonian reflector or refractor of similar aperture and focal length.
