Thousand Oaks Full Aperture Solarlite Filter For Celestron 8" Newtonian Reflectors C8N/C8N-GT

Thousand Oaks SolarLite Solar Filter – For Celestron 8" Newtonian Reflectors (C8N / C8N-GT)

Full-Aperture Solar Protection for 8" Newtonians

Designed specifically for the Celestron C8N and C8N-GT 8" Newtonian reflectors, this Thousand Oaks SolarLite filter brings safe, high-contrast solar viewing to a popular class of large-aperture scopes. Whether you’re chasing an eclipse or tracking evolving sunspot groups, this filter provides the clarity, fit, and durability you need for high-quality solar observing.

At the heart of the filter is Thousand Oaks' proprietary SolarLite film—an advanced material that delivers the resolution of glass with the rugged resilience of polymer. It offers a consistent yellow-orange solar image with excellent contrast and uniform density. Unlike traditional thin-film filters, SolarLite won’t wrinkle, crease, or degrade over time.

The filter’s aluminum mounting cell is felt-lined for a snug, scratch-free fit over your telescope’s front aperture. Lightweight and durable, it won’t throw off your balance or require counterweights, making it ideal for both backyard and travel setups.

Key Features:

• Glass-Like Solar Performance: SolarLite film reveals surface granulation, sunspots, and solar limb detail with sharp contrast

• Custom Fit: Designed specifically for the Celestron C8N and C8N-GT 8" Newtonian reflectors

• Durable and Lightweight: Tear- and puncture-resistant, with a flat, wrinkle-free film surface

• Secure Mounting: Felt-lined aluminum cell provides a firm, protective fit over the telescope’s front aperture

• Ready for the Field: Perfect for both visual observing and solar imaging with Newtonian scopes

Compatibility:
Sized to fit the front cell of Celestron C8N and C8N-GT 8" Newtonian reflectors, or any telescope with an outer tube diameter in the 9.0" to 9.25" range (approx. 228mm to 235mm). Be sure to measure your tube’s outer diameter to confirm fit before ordering.

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.
