The Explore Scientific 2X Focal Extender (2.0-inch O.D.), accepts both 1.25-inch O.D. and 2.0-inch O.D. format eyepieces and camera adapters. Fully EMD-Coated on all air-to-air lens surfaces, with all lens elements edge-blackened to produce superior contrast, this focal extender adds some real versatility to your telescope accessory line-up.

First of all, it allows you to increase the magnification of any eyepiece with the same barrel size that you already own. In other words, 3 eyepieces offer 6 magnification choices with the addition of a focal extender.

Secondly, most of the time, lower magnification eyepieces such as the 30mm 82 Degree Series Waterproof Eyepiece have better eye relief than higher power models. When using a focal extender to increase your magnification, you get to enjoy the generous eye relief of the lower power eyepiece, and that’s quite a bonus, especially for eyeglass wearers or for those with fast telescopes who can really push high magnification eyepieces.

Built with a 2" nosepiece that fits into larger drawtubes, focusers, and diagonals, the Explore Scientific 2" 2x Focal Extender doubles the magnification of any 2" or 1.25" eyepiece and adds another layer of usability to the eyepieces you have.

Plus, since low-power eyepieces often offer a longer eye relief than high-magnification ones, using this focal extender gives you the benefit of a more comfortable viewing experience while enjoying a high-power observational experience.

This extender has a fully multi-coated 4-element lens configuration to produce bright images with true color representation without distortion across the entire field of view, and the edges of the lenses are blackened to further improve contrast.

The extender accepts larger 2" eyepieces and with the included reducer adapter you can also use the smaller and more popular 1.25" size for more versatility.
