The iOptron TFE100 Green Moon Filter reduces irradiation, glare, and excess image brightness during lunar observation. It also improves the contrast between lunar albedo features.
The Green Moon Filter is designed to screw directly into the barrel of 1.25" telescope eyepieces. Its green color cuts the glare of the brightly lit 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.
