Thousand Oaks Solarlite 9.25" Solar Filter For Celestron 9.25" SCT S-10750

Thousand Oaks SolarLite Solar Filter (S-10750) – For Celestron 9.25" SCT

High-Contrast, Full-Aperture Solar Protection for the Celestron 9.25" SCT

The Thousand Oaks SolarLite S-10750 solar filter is precision-engineered for the unique front cell diameter of the Celestron 9.25" Schmidt-Cassegrain Telescope. It’s the perfect solar accessory for safely observing sunspots, solar granulation, and eclipses with one of Celestron’s most popular and optically capable SCTs.

This full-aperture filter features SolarLite, Thousand Oaks’ proprietary solar film that offers the image sharpness of glass with the rugged resilience of polymer. The result is a sharp, evenly illuminated yellow-orange solar disk with excellent contrast and no pinholes, scratches, or creases to degrade performance.

The felt-lined aluminum cell is designed for a snug, scratch-free fit over the front of your 9.25" SCT. Lightweight and field-friendly, the S-10750 won’t affect balance or setup time, making it ideal for both backyard observing and eclipse travel.

Compatibility:
Fits the Celestron 9.25" Schmidt-Cassegrain Telescope. The internal cell diameter accommodates front cells measuring approximately 273mm (10.75"). Be sure to measure your OTA’s front cell to confirm fit.

SolarLite Film Technology:
After years of research and development, Thousand Oaks Optical has introduced SolarLite—a new solar film that delivers the optical sharpness of glass with the durability and resilience of a polymer. Unlike traditional solar films, SolarLite won’t develop pinholes or surface scratches that could compromise safety. It’s lightweight, so it won’t require rebalancing your optical tube assembly, and it's built to withstand the rigors of field use.

SolarLite offers a consistent yellow-orange solar image across the entire aperture with excellent contrast and uniform density. Its smooth, flat surface ensures sharper views compared to other thin-film filters that often suffer from wrinkles and creases. Tear-resistant, puncture-proof, and more rugged than any other solar film available, SolarLite sets a new standard for safe, high-quality solar observing.

Safety Note:
Before each use, inspect your solar filter for any damage or defects. Never observe the Sun without a securely attached, undamaged filter in place.
