These filters are designed to work with our Advanced Series C4-R and NexStar 102 telescope models.

Solar Filters are made with Baader Astro Solar™ Safety Film. Far superior than any existing glass, Mylar or polymer filters,
they lead to brighter, sharper, and higher contrast images.
Enter the new millennium with the finest solar filters
available. Astro Solar™ Safety Film is clear and homogenous and attains the optical performance of high quality
plane-parallel glass filters-it is diffraction limited! Double-sided metal coatings have uniform density and good color balance
across the entire field ensuring razor sharp images from edge to edge.
The Sun appears in its "real "color -neutral white,
not blue or orange ,and the sky adjacent to the solar limb is jet black.
You can see detail in sunspots, bright faculae
near the limb and the mottled areas known as granules with these filters. The Sun offers constant changes and will keep your
observing interesting and fun. Even small aperture telescopes can enjoy features of the Sun.
The Astro Solar™ film is
completely safe and durable (won‘t break like glass if dropped). Its rating is ND-5 which means that the film transmits 1/100,000
of visible light (.001%) while reflecting (blocking) 99.999%of unwanted light. The film absorbs all ultraviolet rays while coating
reflects infrared light rendering both absolutely harmless. For added assurance, Baader Astro Solar™ film has been declared
safe for direct solar viewing by the German National Bureau of Standards for eye safety.
Celestron has previously
manufactured high quality, plane-parallel glass solar filters (unlike today 's glass filters which generally are poor in quality
with reduced contrast). Celestron has offered Mylar solar filters (they were the best previously available) but they suffer from a
lot of scattered light and false color. Polymer filters suffer from not only scattered light but also have reduced sharpness and
contrast due to their increased thickness. So, "we‘ve been there and done that" and after all these years are now offering the
finest solar filters available for observing. Each is mounted in a durable ABS or rubber cell that won‘t break.
