50mm - 100mm Aperture

This collection covers telescopes from 50mm to 100mm of aperture, the compact, grab-and-go end of the range. They are easy to carry, quick to set up and forgiving to align, which suits beginners and travel. Expect strong views of the Moon, planets and double stars.

You will find small refractors from Explore Scientific and National Geographic, with FirstLight models on alt-azimuth and GoTo mounts. Looking for a 4-inch refractor? Ours measure 102mm, so they are in our 101mm to 200mm collection.
