Eyepieces - Like telescopes, eyepieces come in a variety of designs. Each design has its own advantages. For the 1-1/4" barrel diameter there are three different eyepiece designs available:

•OMNI Plössl - Plössl eyepieces have a 4-element lens designed for low-to-high power observing. The Plössls offer razor sharp views across the entire field, even at the edges! In the 1-1/4" barrel diameter, they are available in the following focal lengths: 4mm, 6mm, 9mm, 12.5mm, 15mm, 20mm, 25mm, 32mm and 40mm.

•X-Cel- This 6 element design allows each X-Cel Eyepiece to have 20mm of eye relief, 55° field of view and more than 25mm of lens aperture (even with the 2.3mm). In order to maintain razor sharp, color corrected images across its 50° field of view, extra-low dispersion glass is used for the most highly curved optical elements. The excellent refractive properties of these high grade optical elements, make the X-Cel line especially well suited for high magnification planetary viewing where sharp, color-free views are most appreciated. X-Cel eyepieces come in the following focal lengths: 2.3mm, 5mm, 8mm, 10mm, 12.5mm, 18mm, 21mm, 25mm.

•Ultima - Ultima is not really a design, but a trade name for our 5-element, wide field

eyepieces. In the 1-1/4" barrel diameter, they are available in the following focal lengths: 5mm, 7.5mm, 10mm 12.5mm, 18mm, 30mm, 35mm, and 42mm. These eyepieces are all parfocal.

Exotherm, Hand Warmer- (#93504) - Perfect for chilly evenings of star gazing, the Exotherm Hand Warmer is convenient, reusable and provides up to one hour of instant heat.
