The Vixen 102M is a 102mm (4-inch) achromatic refractor telescope, often praised for its excellent optical quality and solid build despite being an achromat, not an apochromat (APO). It features a long focal length, typically around f/9 or longer, which helps minimize chromatic aberration (color fringing) on bright objects, making it a favorite among visual observers. The telescope is known for delivering crisp views, excellent planetary detail, and a lightweight, robust feel, coming mounted on the Vixen Super Polaris (GP/GPDX) equatorial mount.
