The Altair 15mm Wide Field 70 Degree Telescope Eyepiece is an affordable high quality unit giving a 70 degree apparent field of view for astronomy and for high power daytime terrestrial viewing. The wide field of view lets you take in a lot more than the standard Plossl eyepieces sold with most telescopes, and it's a significant yet affordable upgrade.

The 15mm offers approximately 15mm of eye relief and the eye-cup can be folded down to provide even more comfort to those wearing glasses.

All 8 optical surfaces on the 4 internal glass elements are fully multi-coated to reduce internal reflections, for a higher contrast image. The 1.25" barrel is threaded for filters, and it has an internal blackened thread to stop stray light reflection, increasing image contrast. Plastic end-caps are included. 

A 15mm version of this eyepiece is also available, and we recommend the Altair 2x ED Barlow lens for a complete to give you a wider range of magnifications. 

To work out the magnification this eyepiece produces, simply divide the focal length of the TELESCOPE by the focal length of the EYEPIECE. For example 800mm focal length divided by 15mm = 53.3x magnification.

By using an ED Barlow lens (available separately) you can effectively double the power of this eyepiece, giving you 80x magnification in the above example.
