EclipSmart Safe Solar Eclipse Telescope Filter - ISO-Certified Solar

Our review of the EclipSmart Safe Solar Eclipse Telescope Filter finds it to be a focused, practical accessory for owners of Celestron 5 Schmidt-Cassegrain telescopes who want safe direct views of the Sun. The single biggest reason to buy is safety: the filter conforms to the ISO 12312-2:2015(E) international standard, giving confidence when observing eclipses, sunspots, or daily solar detail. It is simple to fit and is explicitly designed to attach securely to the specified 5 in Schmidt-Cassegrain models, making setup quick for both first-time eclipse viewers and experienced hobbyists.

Key Features

• ISO-Certified Safety: The filter meets the ISO 12312-2:2015(E) standard so users can view the Sun directly with appropriate protection.
• Model Compatibility: Custom-designed to work with Celestron 5 Schmidt-Cassegrain telescopes including NexStar 5SE and StarSense Explorer 5, ensuring a tailored fit.
• Secure Attachment: Two hook and loop straps give a snug, stable hold on the telescope objective to reduce the risk of accidental exposure.
• Made-in-USA Solar Film: The solar film is produced by American Paper Optics in the USA and is independently third-party tested for safety and performance.
• Visual Appearance: The filter produces an orange-tinted view that yields natural-looking solar images suitable for visual observing and basic astrophotography.
• Warranty & Support: Purchase includes a Celestron Limited Lifetime US Warranty and access to US-based technical support for post-sale assistance.

Who It's For

This accessory is aimed at owners of the specified Celestron 5 Schmidt-Cassegrain models who want a dedicated, tested solution for direct solar observing and eclipse viewing. It is best for amateur astronomers who prefer a secure, purpose-built filter rather than improvised solar films or improvised mounts.

Those who should look elsewhere include owners of telescopes other than the listed 5 in Schmidt-Cassegrain models, since the product is custom fit and will not work with other tube diameters or configurations. Also, advanced solar observers seeking narrowband hydrogen-alpha detail will need specialized solar telescopes rather than a white-light safety filter.

Pros & Cons

Pros
