Product Description

Amazon.com Product Description

The Celestron 94162 solar filter for NexStar 8 and 8i SCT telescopes is designed to work with Celestron's NexStar 8-inch SCT telescopes (Schmidt-Cassegrain Telescope). While this unit is made to work specifically with the NexStar 8 SE and NexStar 8i XLT Special Edition SCT telescopes, it can be used with other compatible 8-inch SCT telescopes as well.

This Celestron solar filter is made with Baader Astro Solar safety film, which is far superior to any existing glass, Mylar or polymer filters, leading to brighter, sharper, and higher contrast images. This filter is clear and homogenous, attains the optical performance of high-quality, plane-parallel glass filters, and is diffraction limited. The double-sided metal coatings have uniform density, providing good color balance across the entire field, which in turn ensures razor sharp images from edge to edge. The 94162 filter causes the sun to appear in its true color of neutral white, rather than blue or orange, with the sky adjacent to the solar limb a jet black. This unit reveals the constant changes that keep solar observing fun and interesting, allowing you to see the detail in sunspots, bright faculae near the limb, and the mottled areas known as granules, so that even small aperture telescopes can enjoy features of the sun.

The Astro Solar film in this filter is completely safe and durable, so it won't break like glass if dropped. This filter's ND-5 rating means the film transmits 1/100,000 of visible light (or 0.001-percent), while reflecting or blocking 99.999-percent of unwanted light. The film absorbs all ultraviolet rays, while its coating reflects infrared light, rendering both absolutely harmless. As an added assurance, Baader Astro Solar film has been declared safe for direct solar viewing by the German National Bureau of Standards for eye safety. Each 94162 solar filter is mounted in a durable ABS (Acrylonitrile butadiene styrene) plastic and rubber cell that won't break and is highly resistant to heat distortion, and is backed by a 1-year manufacturer's warranty.
