The barlow increases the magnification of any 2 inch or 1.25 inch eyepiece by two and a half times
Rubber grip for easy handling in cold weather or with gloves
Neutral density filters are excellent filters to reduce the overall brightness of an image to cut down glare while viewing bright astronomical objects through a telescope
These three ND moon filters are useful for splitting binary systems; comfortably observing the moon; or stacking with other planetary filters
ND filters retain true color balance of the objects being observed since all wavelengths are transmitted uniformly over the entire spectrum
Description
2" Barlow inserts between the eyepiece and a 2" eyepiece holder on the telescope and increases the magnification by 2.5x. It can be used with 1.25" eyepiece and 2" eyepieces. The 4-element fully multicoated lens assembly offers superb field flatness and minimal chromatic aberration.
