Review: I stared at the sun and am not blind yet. - Bought it for the 2024 eclipse, worked pretty well. It attached easily to my budget telescope and I did not go blind while staring at the sun through it, so I count it as a success. Review: Does the job - Works great for viewing the sun safely with my 70AZ. Seems overpriced for what you get though... just a plastic cap with the same kind of solar film as those cardboard eclipse glasses. For $25 I'd feel better if the filter was made of plastic. The film works, but it's cheap and fragile. One accidental bump and you'd likely ruin it. ## Features - SOLAR SAFE TELESCOPE FILTER: Filter conforms to the ISO 12312-2:2015(E) international safety standard for filters directly viewing the Sun.

It attached easily to my budget telescope and I did not go blind while staring at the sun through it, so I count it as a success. ### ⭐⭐⭐⭐⭐ Does the job *by L***S on March 1, 2024* Works great for viewing the sun safely with my 70AZ. Seems overpriced for what you get though... just a plastic cap with the same kind of solar film as those cardboard eclipse glasses. For $25 I'd feel better if the filter was made of plastic. The film works, but it's cheap and fragile. One accidental bump and you'd likely ruin it. ### ⭐⭐⭐⭐ It works, for the most part. *by W***L on March 27, 2024* I'm not blind yet, so the filter clearly works quite well. What doesn't work as well are the attachment thumbscrews. They're cheap plastic, and break incredibly easily. Luckily my 70mm refractor makes for a Snug Fit without the screws, but that could cause a huge (and dangerous) issue for telescopes that are smaller. The screws need to be swapped for metal ones. ## Frequently Bought Together - Celestron – EclipSmart Safe Solar Eclipse Telescope Filter – Meets ISO 12312-2:2015(E) Standards – Works with Existing 70mm AZ & EQ Telescopes – Observe Solar Eclipses and Sunspots – Safe, Snug Fit - Celestron – Smartphone Photography Adapter for Telescope – Digiscoping Smartphone Adapter – Capture Photos and Video Through Your Telescope or Spotting Scope Eyepiece - Celestron - AstroMaster 70AZ Telescope - Refractor Telescope - Fully Coated Glass Optics - Adjustable Height Tripod – Bonus Astronomy Software Package --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/529656603-eclipsmart-safe-solar-eclipse-telescope-filter-meets-iso-12312-2](https://www.desertcart.co.uk/products/529656603-eclipsmart-safe-solar-eclipse-telescope-filter-meets-iso-12312-2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-22*
