Manufactured by: Explore Scientific


The Explore Scientific 127mm f/7.5 Air-Spaced Triplet ED APO Refractor is excellent for both planetary and deep sky observation. The optical tube consists of an air-spaced design mounted in an adjustable lens cell using HOYA FCD1 ED glass that reduces chromatic aberration. Moon details will look simply outstanding and sharp with these high quality optics. This mid focal ratio with the elimination of chromatic aberration makes high quality CCD imaging a plus. Due to the sharp images this telescope can produce, appropriate focusing is absolutely critical, so Explore Scientific has included a two-speed Crayford-style precision focuser with tension adjustment to make focusing less of a frustration and easier.
