The Explore Scientific Variable Polarizing Filter is a 2-inch telescope filter that lets you dial in exactly how much light reaches your eye — ideal for taming the glare of the Moon and bright planets. Two stacked polarizing elements rotate against each other to continuously adjust brightness, so you can fine-tune the view for the most comfortable, detailed image.

Who it's for

Lunar and planetary observers who want adjustable glare control in a single filter, rather than a fixed-density Moon filter. New to filters? See our guide to the best telescope filters for beginners.

Key features

  • Continuously variable brightness — rotate to set transmission from roughly 1% to 40%
  • Tames glare on the Moon and bright planets for more comfortable, higher-contrast views
  • Standard 2" threaded cell — fits 2" eyepieces and diagonals
  • No color shift — neutral dimming preserves natural tones

Frequently asked questions

How is this better than a fixed Moon filter?
A fixed neutral density filter gives one brightness level; this one lets you adjust the dimming continuously to match the Moon's phase, your telescope's aperture, and your comfort.

Does it fit 1.25" eyepieces?
This is the 2" version, for 2" eyepieces and diagonals. Use a 2"-to-1.25" adapter if needed, or choose a 1.25" filter for 1.25" eyepieces.

Can I use it on planets?
Yes — reducing glare on bright Venus and Jupiter can reveal more subtle detail.

With a beginner telescope you can see a surprising amount — the craters and mountains on the Moon, the rings of Saturn, the moons of Jupiter, and star clusters like the Pleiades.
