You will find that additional accessories for your Omni telescope will enhance your viewing pleasure and expand the usefulness of your telescope. This is just a short listing of various accessories. Visit the Celestron website for complete and detailed accessories available.
Barlow Lens - A Barlow lens is a negative lens that increases the focal length of a telescope. Used with any eyepiece, it doubles the magnification of that eyepiece. Celestron offers several Barlow lenses in the 1-1/4" size. The 2x Ultima Barlow (# 93506) is a compact triplet design that is fully multicoated for maximum light transmission. The Omni Barlow (# 93326) is a compact achromatic Barlow lens that is less than three inches long and weighs only 4 oz. and it works very well with all Celestron eyepieces.
Collimation Eyepiece 1 ¼” – # 94182 --The collimation eyepiece is ideal for precise collimation of Newtonian telescopes and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1 ¼” focusers and diagonals.
Eyepieces - Like telescopes, eyepieces come in a variety of designs. Each design has its own advantages and disadvantages. Below are just some of the eyepieces 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 55° 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 in 1 ¼” barrels: 2.3mm, 5mm, 8mm, 10mm, 12.5mm, 18mm, 21mm, and 25mm.
