Optional Accessories
ing focal lengths: 2.5mm, 4mm, 5mm, 6mm, 9mm, 10mm, 12mm and
15mm. An 8-24mm zoom eyepiece is also available in the LV series.
In addition to the previously mentioned, there is also a deluxe compact zoom
ocular (#93306) that has a variable focal length of 6.5 to 18mm. This provides
50 to 138 power on the C4.5.
Eyepiece Filters - To enhance your visual observations of planetary objects,
Celestron offers a wide range of colored filters that thread into the 1-1/4"
oculars. Available are: #12 Deep Yellow, #21 Orange, #25 Red, #58 Green,
#80A Light Blue, #96 Neutral Density (25%, and 13% transmission) and
Polarizing filters. The filters are sold separately (or some are available in
sets) so you can buy them individually as you need them!
LED Flashlight (#93592) - The LED flashlight uses a red light emitting diode
(LED) to allow reading star maps and locating telescope accessories and
functions without ruining your night vision. The LED flashlight is small,
only 6 inches long, and weighs in at a mere 3 ounces.
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).
Micro Guide Eyepiece (#94171) - This multipurpose illuminated 12.5mm
reticle can be used for guiding, measuring position angles, angular separa-
tions, and more. The laser etched reticle provides razor sharp lines and the
variable brightness illuminator is completely cordless. The micro guide
eyepiece produces 72 power when used with the C45.
Motor Drive with Drive Corrector - This unit is a motor drive and drive
corrector in one. It is a necessity if you want to do any form of celestial
photography. For the C4.5 we offer a single axis model which runs off DC
power (#93516). The drive corrector function allows you to manually
override the motors for corrections during celestial photography.
Polar Axis Finder Kit (#93605) - This accessory aids in the polar alignment
process by improving the accuracy of your alignment and also reducing the
alignment time. The kit includes a finder (15mm diameter objective lens,
3.5x magnification, 6° field of view) with eyepiece diopter adjustment,
illuminated cross hair reticle, a 1.5 volt 'AA' battery, and instruction sheet.
Polarizing Filter Set (#93608) - The polarizing filter assembly limits the
transmission of light to a specific plane, thus increasing contrast between
various subjects. This is used primarily for terrestrial, lunar, and planetary
observing.
Sky Maps (#93722) - When learning the night sky, the Celestron Sky Maps
offer the ideal solution. The maps include all the constellations with the
brighter deep-sky objects. The maps are printed on a heavy stock paper that
is moisture-resistant. On the front cover is a rotating planisphere which
indicates when specific constellations are visible.
