Advanced Telescopes

Advanced Telescopes gathers our highest-tier instruments for serious visual observers and astrophotographers who judge a scope by its optics first. The defining trait is premium optical quality with real aperture, from apochromatic triplet refractors to large-aperture reflectors.

You will find Explore Scientific FPL53 ED triplet apo refractors on carbon-fiber tubes, in 115mm through 165mm, plus a 20-inch truss-tube Dobsonian for deep visual reach. Weigh aperture and focal ratio against your targets and mount when stepping up to this tier.
