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 two Barlow lens in

the 1-1/4" size for the NexStar. The 2x Ultima Barlow (#93506) is a compact triplet design that is

fully multicoated for maximum light transmission and parfocal when used with the Ultima eyepieces.

Model #93507 is a compact achromatic Barlow lens that is under three inches long and weighs only 4

oz. It works very well with all Celestron eyepieces.

Diagonal, 45 degree, erect image (#94112-A) – This design allows you to look into the telescope at a 45° angle, at images that are oriented

properly, meaning the image is upright and correct from left to right.

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.

Filters, Eyepiece - To enhance your visual observations of solar system objects, Celestron offers a wide range of colored eyepiece filter sets

filters or other devices. Brightness is adjustable. Operates on a single 9 volt battery (included).

Light Pollution Reduction (LPR) Filter - These filters are designed to enhance your views of deep sky astronomical objects when viewed

from urban areas. LPR Filters selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial

ill find that additional accessories enhance your viewing pleasure and expand the usefulness of your telescope. For ease of refere

accessories are listed in alphabetical order.
