Alstar 2" 2.5X Barlow Lens - Bundle with - 2" Telescope Moon Filter Kit

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.

• 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
