  • Reduces glare and boosts lunar contrast for detailed observation
  • Three neutral-density filters with 13%, 25% and 50% transmission for every phase
  • Standard 1.25" thread fits most telescope eyepieces
  • Premium glass minimizes light pollution and preserves natural colour balance
  • Supplied in a protective carrying case for safe storage

Lunar Viewing Filter Set

The Celestron Moon Filter Set contains three neutral-density filters for 1.25 inch telescope eyepieces. They reduce glare and improve contrast so that surface detail on the Moon becomes clearer. The set is intended for amateur and advanced astronomers who want better lunar views. A carrying case keeps the filters protected when not in use.

Simple Threaded Installation

Each filter screws into the standard 1.25 inch thread found on most telescope eyepieces. No tools are required and the filters can be swapped in seconds. The only common issue is cross-threading if the filter is forced; aligning the threads carefully avoids this. Clean the glass with a lens cloth before first use to remove any dust.

For Visual Lunar Observers

This set suits anyone who observes the Moon visually and wants adjustable brightness control across different phases. The three densities provide 13, 25 and 50 percent transmission options. It does not suit imagers who need narrowband or colour filters for planetary photography. Buyers who use 2 inch eyepieces exclusively will need a different thread size.

Questions about this item

How can I verify the filters are working correctly after attaching them to my telescope?

You should notice reduced glare and improved contrast on the lunar surface, with faint details like craters becoming more visible without any colour distortion across all three filters.

What comes in the box and do I need to buy anything else to use them?

The set includes the ND96-0.9, ND96-0.6, and ND96-0.3 filters in a carrying case; they thread directly into any standard 1.25" eyepiece so no extra adapters are required.

Which filter density should I choose for a full Moon versus a crescent?

Use the ND96-0.9 at 13% transmission for a bright full Moon, the ND96-0.6 at 25% for gibbous phases, and the ND96-0.3 at 50% for thinner crescents or smaller apertures.
