Description

The Opticstar ARC-127 optical tube assembly is a 127mm aperture F/9.5 achromatic refractor with high quality optics that is ideal for planetary, Lunar and Solar observing with an appropriate Solar filter. Its relatively large aperture also makes it suitable for deep sky work to a degree.

Optical Design

The ARC-127 uses an objective consisting of two Low Dispersion (LD) Crown/Flint lenses, the lenses are broadband anti-reflection multi-coated for increased contrast and sharpness. The LD objective in conjunction with a long focal ratio restrains optical/chromatic aberrations in general and making the telescope well suited for high power work.
