Who said you have to be in the dark to do astronomy! Turning your telescope to the Sun is fun and educational. Watch the march of giant sunspots, the clouds of glowing vapor in the photosphere, and solar “granulation” detail. Never miss a partial / Total Solar Eclipse or rare events like Transit of Venus and Mercury. But be sure to protect your precious vision with a safe Astro Solar Safety film Filter! Looking at the Sun without proper safety filter, even for an instant, can permanently damage your eyes.

Features and Specifications:
•Our Astro Solar Safety film Filters are made from the famous white light Baader AstroSolar™ safety film made in Germany.
•The filter cells are made of tough ABS plastic or cast metal and most are fitted with nylon thumbscrews for a secure fit.
•The filter film is mounted in its own cell, unlike many other commercially sold filters where the film is simply glued on to the inner rim of the cell without any reinforcement.
•Astro-Solar filter is a very flexible substance by nature. When mounted in the filter cell, it will be quite wrinkled. Don’t be upset by the appearance because the best resolution is obtained when the material is slightly relaxed or wrinkled
