Precise scientific measurements show the moon reflects, on average, about 12% of the sunlight that falls upon it. That makes it, on average, about as reflective as an asphalt driveway. But if you’ve ever looked at a thickening gibbous moon through even a moderately-sized telescope, it can appear uncomfortably bright to the dark-adapted eye.
That’s why many visual lunar observers and lunar imagers consider filters to reduce the brightness and glare of the moon so they can see finer detail during a long observing session.
- Reduces irradiation, glare, and excess image brightness in lunar observing.
- Improves the contrast between lunar albedo features.
- Will screw directly into the barrel of most 1.25″ eyepieces.
- Green color cuts the glare of the brightly-lighted Moon and improves the contrast so it is easier for you to see faint details that might otherwise be washed out by the brightness of the lunar surface.
