SkyWatcher Solar Filter 180mm for Maksutov-Cassegrain

NOTE: Never look at the Sun through your telescope without properly installing a filter first. It could cause irreversible damage to your eyes!

The Sky-Watcher 180mm Solar Filter is designed for safe and effective solar observation with Maksutov Cassegrain telescopes. This filter attaches securely to the front of your telescope, allowing you to view the Sun safely by reducing its intensity and filtering out harmful rays.

Made with Baader Astro Solar Safety Film, this filter delivers high optical performance akin to plane-parallel glass filters. The film features double-sided metal coatings that ensure excellent color balance, allowing you to view the Sun in its natural white light.

With this filter, you can observe sunspots, bright faculae near the solar limb, and the granular surface of the Sun with clarity. The filter transmits only 1/100,000 of visible light while reflecting 99.999% of unwanted light, significantly reducing ultraviolet and infrared rays. The Baader Astro Solar™ film has been certified for direct solar viewing by the German National Bureau of Standards, ensuring its safety and durability.

This solar filter is specifically designed for 180mm Mak telescopes, making it a practical choice for enthusiasts looking to explore the dynamic features of our closest star.
