William Optics Fluorostar 132 F/6.9 APO Refractor Telescope (Gray)

The William Optics Fluorostar 132 F/6.9 APO is a highly acclaimed telescope in the world of professional astrophotography. Celebrating its fourth iteration in 2021, this model introduces significant enhancements, including a 3.7-inch diameter lift, to elevate your astrophotography experience.

At the heart of this exceptional refractor is an apochromatic triplet optical system with an air gap. Crafted from premium FPL-53 glass by the esteemed Japanese company Ohara, this material is renowned for its superior optical qualities. With an impressive Abbe number of 94.49, comparable to crystalline fluorspar, the FPL-53 glass ensures minimal chromatic aberration and delivers crystal-clear, high-contrast images. All lenses are equipped with a multi-layer anti-reflective STM coating for optimal performance.

This refractor's generous illumination disc diameter makes it perfect for use with full-frame or APS-C sensor cameras, ensuring comprehensive coverage for your imaging needs.

Constructed with steel lens mounts, the Fluorostar series is designed to withstand temperature fluctuations. When not in use, it is recommended to remove the lens hood to allow moisture to evaporate, preventing potential corrosion of the lens mounts.
