Astro Essentials 1.25" Moon 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.

Moon Filter

The Moon can be quite bright especially when gibbous or close to full, producing a lot of glare. This can dazzle the observer making it difficult to see fine detail. This filter reduces the brightness by 18% for more comfortable viewing. It also improves contrast so enhances surface features.

Due to the wavelengths of light passed this filter imparts a slight green tint. 

NOTE: Manufactured using optical glass with dyed-in-the-mass colour mounted in a machined metal cell (unlike some truly awful plastic copies available elsewhere).
