Altair Wide Field 15mm Eyepiece

The Altair Wide Field 15mm Eyepiece is a 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. 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. All 8 optical surfaces on the 4 internal glass elements are fully multi-coated to reduce internal reflections, for a higher contrast image.

The Altair Wide Field 15mm Eyepiece

To work out the amount of magnification this eyepiece produces with your telescope, 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.
