Astro Essentials Moon Filter 1.25" ND 0.6

Reduces unwanted glare when observing the Moon and planets. 

This neutral density filter allows 25% of visible light to pass through. Only one-quarter of the amount of light passes through into the eyepiece, making the image 4x 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.

  • Premium optical glass with dyed-in-the-mass colour mounted in a precision metal cell

Quite good!

I wanted to order the Baader ND filter but was out of stock so I took the plunge and ordered this instead. I used it on the Moon and Jupiter and I am quite happy with this. The anti-reflective coatings are not as good as the Baader ND filter (I have the 0.9) but for the price it is great. I observed the Moon at 100x-170x and just as sharp with as many details if I observed without the filter. Great!
