Information:
The ND96 0.9 Astronomica Moon Filter reduces glare; allowing transmission of only a portion of the Moon's reflected light. Not only will you see more surface features; but you can study them in greater comfort. The filter reduces irradiation; which is the distortion at the boundary between light and dark areas; such as along the lunar terminator. The Filter is especially useful to owners of large-aperture scopes; in which the Moon's brightness can be overwhelming. It uniformly reduces light over the entire visible spectrum. Screws into threaded eyepiece barrel. The 0.9 version has been measured to transmit 13% of the incident light. |
Specifications:
