Celestron Solar Filter Mylar for C4 R/FirstScope/102AZ

Celestron 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

This is a safe full aperture solar filter. This means that it allows the most light possible into the telescope because it allows the full aperture of your telescope to be viewed. The full aperture allows the best possible daytime viewing when there is minimal atmospheric turbulence.This premium solar filter has an aluminum cell that is secured to the tube end of the telescope with a nylon thumb screw. The clear aperture is made with high quality hand selected and inspected reflective coated glass. This is the highest quality, most durable, 6" full aperture glass solar filter on the market. The sun is safely viewed in a natural yellowish-orange image. The neutral density is 5 - 5.5. The filter can be used for direct viewing through the telescope or for photography. It will fit a telescope with a tube end (opposite the eyepiece) diameter of 5 7/8"(149mm) to 5 5/8"(143mm). You can measure the diameter of the end of your telescope to see if this filter will fit. This filter is new in the box in plastic. The filter box is foam lined for protection and shock absorption during handling. It is durable enough to store the filter while not in use. Included with this filter are instructions for use and care.
