Explore Scientific 3X2" Focal Extender

Introducing this High quality and functional 3X2" Focal Extender by Explore Scientific. This 3X Focal Extender (2.0-inch O.D.) obtains both 1.25-inch O.D. and 2.0-inch O.D. camera adapters and format eyepieces. On all air-to-air lens surfaces, It is Fully EMD-Coated with all the lens elements edge-blackened to generate superior contrast; this focal extender adds real versatility to your telescope accessory line-up.

First, it allows you to increase the magnification of any eyepiece with the same barrel size you already own. In other words, three eyepieces offer six magnification choices, including a focal extender.

Secondly, lower magnification eyepieces such as the 30mm 82 Degree Series Eyepieces have better eye relief than higher power models. When using a focal extender to boost your magnification, a quiet bonus is that you enjoy the giving eye relief of the lower power eyepiece, those with fast telescopes who can push high magnification eyepieces or especially for eyeglass wearers. Remember, we also offer 1.25-inch O.D.

Focal Extenders are also in 2X, 3X, and 5x models, so there is something for every style of telescope.
