101mm - 200mm Aperture

This collection covers larger-aperture telescopes from 101mm to 200mm, the step up from a small starter scope. More aperture means greater light grasp, so faint deep-sky objects look brighter and planetary detail resolves more finely. It suits observers ready to push past the basics.

The mix spans Explore Scientific and National Geographic refractors and Newtonian reflectors, from FirstLight doublet refractors to carbon-fiber reflectors. When choosing, weigh aperture against focal ratio and mount type for your targets.
