To ensure that the solar filter you buy will fit properly, please take a few moments and measure the outside diameter of your telescope, spotting scope or binoculars before you order. Remember, the solar filter needs to fit snugly around the front of the tube assembly that holds the optics. If the filter is slightly larger than its diameter, the filter can be made to fit by the addition of self-stick felt spacers to the inside of the cell. However, if the filter is too small it will not fit, and that would be a shame. So please, measure before you order. Thanks.

Spectrum Film Solar Filter - 92 mm - 98 mm OD


This Spectrum Film Solar Filter fits the following instruments:

  • Celestron 80 (old)
  • Meade DS-70, ETX-80 AT-TC, DS 2080
  • Orion ShortTube 80, Observer 70, Astroview 80/90, Explorer 80/90
  • Takahashi SKY 9011

  • Swarovski AT80, STS 80, STS 80 HD Spotting Scope


The aluminum cell of this durable premium solar filter is centered and attaches to the end of the optical tube using felt padding via nylon thumb screws. The film in this filter permits as much light as possible through the telescope. This allows the full aperture of the telescope to be used. Full aperture filters are extremely useful when the atmosphere is less turbulent. The film is made from 0.002" thick black poly plastic, which is a durable thin film. With proper use, this can last for many years!

This filter arrives in a foam-lined box with plastic wrapping to prevent any possible damage during shipping. The box is also useful as a means of storing the filter between uses. Complete instructions detailing correct use and maintenance are included.

In order to assure a proper fit, please be sure to measure the outside diameter of your telescope before committing to purchase a specific solar filter as telescope specifications may be modified with subsequent versions due to re-designs, etc.
