Feature:
The filter will fit all standard sized 1.25 eyepieces and accessories. Reduces glare and improves definition so you can see the moon's features. A high quality eyepiece filter for reducing the brightness of the moon and improving contrast and surface detail. A moon filter really makes a difference and at such a low cost is a must for every astronomer. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulas.
