Astro Essentials Moon Filter 1.25" ND 0.3

Reduces unwanted glare when observing the Moon and planets. 

This neutral density filter allows 50% of visible light to pass through, so only half the light entering the telescope passes through into the eyepiece, making the image 2x fainter.

Premium optical glass with anti-reflection coatings and a neutral density (doesn't affect colour). 

Screws into the standard 1.25" filter thread of eyepieces and accessories. It can also be stacked with other filters. 

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

Top delivery once again - Under 24 hours. Bought all 3 ND filters plus 2 others. Buy 4 get 1 free. Brilliant. Not had chance to use them yet due to the 'Free Clouds' that came with the box, but must say, build quality is excellent. FLO is my 1st stop every time.
