The Celestron EclipSmart filter is a solar-safe tool designed for direct solar viewing and eclipse photography. It conforms to ISO 12312-2:2015(E), meeting international safety standards for solar filters. The filter is compatible with telescopes, spotting scopes, or DSLR cameras with objective lenses between 75mm and 100mm in diameter. It features adjustable side panels for a secure fit and folds flat for compact storage. This makes it a flexible option for observers who switch between different optical devices while chasing a total solar eclipse.
Key features include ISO safety compliance, compatibility with multiple optical devices, and a secure, fold-flat design for easy transport. Suitable for both visual viewing and photography when used with appropriately sized equipment.
Celestron 94243 EclipSmart Solar Eclipse Filter
The Celestron 94243 EclipSmart filter is designed for 6” Schmidt-Cassegrain telescopes, offering ISO 12312-2 compliance and a secure, two-strap hook-and-loop attachment system. This solution emphasizes a snug fit to minimize stray light and ensure consistent exposure during crucial moments of the eclipse. It is intended for users who already own a Celestron 6″ SCT and want a trusted option from the same brand.
Highlights include a standardized fit for popular SCT models, ISO safety compliance, and a simple secure-attachment design that helps maintain alignment during dynamic viewing and photography sessions.
Thousand Oaks Optical 6″x6″ Solar Filter Sheet
This 6×6 inch solar filter sheet uses a silver-black polymer filtering material common for sunspot and granulation observations. It is designed for DIY filter construction for telescopes, binoculars, or cameras, offering a cost-effective option for enthusiasts who prefer a tailored fit. The filter presents the Sun in a natural orange hue when viewed through a telescope, aligning with expectations for solar viewing materials.
Ideal for DIY projects, this sheet provides a balance of affordability and customization, with the understanding that proper assembly and secure mounting are essential for safe operation.

Another solar filter sheet option from Thousand Oaks Optical, sized 4×4 inches, designed for easier integration with smaller setups or DIY projects. The black polymer material provides reliable attenuation for solar viewing and photography, with a long-standing reputation from a manufacturer focused on safe solar filters for decades. This sheet enables custom filter solutions for a range of devices, from compact cameras to small telescopes.
As with all DIY solar filters, careful handling, proper mounting, and verification of a secure fit are essential to ensure safe operation and optimal image results during eclipse events.
Seymour Solar Hyperion Solar Film Sheets
The Hyperion Solar Film Sheets by Seymour Solar offer a compact solution for solar photography and viewing, with a 3.5″ x 5″ format. The film reduces the Sun’s brightness and harmful rays by up to 99.999%, enabling safe observation of surface details such as sunspots. This film is ISO 12312-2 compliant and can be attached to most telescope, binocular, or camera setups with a secure fit. It also supports DIY filtering, allowing users to craft their own solar filters for various devices.
Key points include very high attenuation, ISO compliance, versatile mounting, and suitability for both viewing and photography of solar features during eclipses.
Buying Guide: Key Purchase Considerations For Solar Eclipse Filters
When selecting camera filters for solar eclipse work, consider safety, compatibility, and image quality. Below are practical factors and comparisons to help guide your decision.
- Safety compliance: ISO 12312-2:2015(E) compliance is essential for direct solar viewing. Choose filters with verified safety standards to protect eyes and camera sensors.
- Device compatibility: Filters range from telescope-specific to universal sheets. Match the filter type to your equipment (telescope, binoculars, camera lens, or smartphone) and the objective diameter or mounting method.
- Durability and construction: Solid attachments and seals prevent light leaks. For DIY sheets, secure mounting and protective edging reduce the risk of cracks during handling.
- Image quality considerations: Some filters impart color shifts or reduce brightness differently. If possible, review sample photos or test with calm solar scenes to gauge color fidelity and exposure behavior.
- Ease of use and portability: Fold-flat designs, simple strap attachments, or compact sheets improve field usability when chasing a fleeting totality.
- Filter type trade-offs: Solar eclipse filters are purpose-built for safe solar viewing; ND filters (ND1000000) are useful for broad neutral density needs but are not a substitute for proper solar filters in eclipse contexts. Always pair a solar filter with the intended solar photography workflow.
- DIY vs. ready-made: DIY solar filter sheets provide affordability but demand careful handling and correct sizing. Ready-made filters typically offer reliable fit and quicker setup for live viewing and photography.
For photography, plan to test exposure levels ahead of peak moments and have manual exposure control ready. If using a smartphone with a filter, maintain a stable setup and consider a tripod or steady mount to reduce motion blur during brief totality windows.
