widest possible field of view with a 1-1/4" diagonal and is ideal for the NexStar with or without the
Reducer/Corrector.

X-CEL - Fully Multi-coated. All air-to-glass surfaces have 5 layer multi-coating. Field of view 55°. Six
element optical design using ED glass on most curved elements. Parfocal – little to no focusing
adjustments are needed when switching from a low power to high power eyepiece. 20mm eye relief
and soft rubber eyecups. Blackened lens edges to minimizes internal reflection and improved contrast.
Each eyepiece comes in a durable plastic case.
Filters, Eyepiece - To enhance your visual observations of solar system objects, Celestron offers a wide range
of colored eyepiece filter sets that thread into the 1-1/4" oculars. Available sets are:
#94119-10 – Orange, Light Blue, ND13%T, Polarizing (#s 21, 80A, 96ND-13, Polarizing)
#94119-20 - Deep Yellow, Red, Light Green, ND25% T (#s 12, 25, 56, 96ND-25)
#94119-30 - Light Red, Blue, Green, ND50% T (#s 23A, 38A, 58, 96ND-50)
#94119-40 - Yellow, Deep Yellow, Violet, Pale Blue (#s 8, 15, 47, 82A)
Night Vision Flashlight - (#93588) - Celestron’s premium model for astronomy, using two red LEDs to preserve
night vision better than red filters or other devices. Brightness is adjustable. Operates on a single 9 volt battery
(included).
Light Pollution Reduction (LPR) Filters - 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 lights. This includes mercury and high and low
pressure sodium vapor lights. In addition, they also block unwanted natural light (sky glow) caused by neutral
oxygen emission in our atmosphere. Celestron offers a model for 1-1/4" eyepieces (#94126A) and a model that
attaches to the rear cell ahead of the star diagonal and visual back (#94127A).
Micro Guide Eyepiece (#94171) - This multipurpose 12.5mm illuminated reticle can be used for guiding deep-
sky astrophotos, measuring position angles, angular separations, and more. The laser etched reticle provides
razor sharp lines and the variable brightness illuminator is completely cordless. The micro guide eyepiece
produces 163 power when used with the NexStar 8i at f/10.
Moon Filter (
#94119-A) - Celestron’s Moon Filter is an economical eyepiece filter for reducing the brightness of
the moon and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is
21mm and the transmission is about 18%.
Piggyback Mount, NexStar 8i (#93598) - A great accessory for all observers interested in deep-sky
astrophotography, particularly beginners. This mount allows you to attach your camera,
with its lens, to either the top or side of the telescope, making it possible to shoot with a
normal or wide angle lens while guiding through the telescope.
PowerTank (#18774) – 12v 7Amp hour rechargeable power supply. Comes with two 12v
output cigarette outlets, built-in red flash light , Halogen emergency spotlight. 120v AC
adapter and cigarette lighter adapter included.
Polarizing Filter Set (#93608) - The polarizing filter set limits the transmission of light to
a specific plane, thus increasing contrast between various objects. This is used primarily
for terrestrial, lunar and planetary observing.
Radial Guider (#94176) - The Celestron Radial Guider
®
is specifically designed
for use in prime focus, deep sky astrophotography and takes the place of the T-
Adapter. This device allows you to photograph and guide simultaneously through
the optical tube assembly of your telescope. This type of guiding produces the
best results since what you see through the guiding eyepiece is exactly
reproduced on the processed film. The Radial Guider is a “T”-shaped assembly
that attaches to the rear cell of the telescope. As light from the telescope enters
the guider, most passes straight through to the camera. A small portion,
however, is diverted by a prism at an adjustable angle up to the guiding eyepiece.
This guider has two features not found on other off-axis guiders; first, the prism
