Astro Essentials 1.25" #80A Medium Blue Filter

Astro Essential colour filters for astronomy are most often used to enhance contrast when observing the Moon and planets.

Results depend on seeing conditions, the telescope and the target being observed or photographed but the right filter can make a significant difference when, for example, viewing the lunar surface or teasing detail from Jupiter's weather bands or Saturn's rings. 

See our handy guide to colour filters and how they can help improve your lunar and planetary visual observing.

Purchased 4 filters and 1 included for free. The medium blue filter really brightens up a daytime sky and enhances the planets. Used it on Mars so far and it works great.
