About this item

  • 90mm .50" SolarLite Filter for 80mm .15" instruments. This filter should fit the following telescope models: TV Ranger, Williams Optics ZS66 and instruments of similar outer diameter. Part # S3500.
  • Please read carefully: 90mm .50" is the diameter of the filter. The filter fits like a cap by friction. To be absolutely sure that the filter will fit, please measure the outer diameter of your instrument and make sure that it is not larger.
  • SolarLite filters have the optical quality of the glass with the advantages of impregnated polymer (Thousand Oaks Optical Black Polymer). The sun will appear in a natural yellow-orange color when viewed through your telescope using this filter.
  • This is a high quality product of Thousand Oaks Optical (Arizona), a manufacturer of safe solar filters for over 30 years. Words of the producer: stronger than any other solar film on the market. Guaranteed 15 years.
  • WARNING: ALWAYS MAKE SURE THE FILTER IS WELL ATTACHED TO THE TELESCOPE/BINOCULARS/CAMERA. IN CASE NECESSARY, USE STICKY TAPE TO SECURE IT. NEVER OBSERVE SUN WITHOUT A PROPERLY ATTACHED FILTER!

This is an excellent white light filter for looking at the sun with a small refractor. Sunspots are easy to see, works well with an attached camera. Was great during the last solar eclipse. I have a similar filter of the same size from the same brand, but made with glass, and this one with the polymer film is just as good, but obviously less durable than glass. I would prefer the glass, but optically and functionally, I can't tell the difference. Highly recommend.
