Filters, Eyepiece (94119-10) –
Eyepiece filters are an invaluable aid
in lunar and planetary observing . They
reduce glare and light scattering,
increase contrast through selective
filtration, increase definition and
resolution, reduce irradiation and
lessen eye fatigue . Celestron’s
filters are made of high quality, solid
plane parallel glass with excellent
homogeneity. They’re anti-reflection
coated to prevent glaring and ghosting. All eyepiece filters are threaded
to fit Celestron’s, and most other manufacturer’s, 1.25” eyepieces, and
offer a full 26 mm clear aperture. Kit includes: 21, 80A, #15, ND-25
Neutral Density .
Flashlight, Night Vision (#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 .25” eyepieces (#94123) and 2” eyepieces (#94124) .
PowerTank (#18774) – 12v 7Amp hour
rechargeable power supply . Comes with
two 12v output cigarette outlets, built-in
red flash light , LED emergency spotlight.
120v AC adapter and cigarette lighter
adapter included. Celestron also offers a 17
amp hour models (#18777).
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 and eyepiece
housing rotate independently of the
camera orientation making the acquisition
of a guide star quite easy . Second, the
prism angle is tunable allowing you to look at guide stars on-axis . This
accessory works especially well with the Reducer/Corrector .
T-Adapter – This T-Adapter allows you to
attach your 35 mm DSLR camera to the
prime focus of your EdgeHD telescope .
This arrangement is used for terrestrial
photography and short exposure lunar and
planetary photography. It can also be used for
long exposure deep-sky photography when
using a separate guidescope. Model #93644
for CPC Deluxe 800 HD and Model #93646 for
CPC Deluxe 925 and 1100 HD .
T-Ring – The T-Ring couples your 35 mm SLR camera body to the
T-Adapter, radial guider, or tele-extender . This accessory is mandatory
if you want to do DSLR photography through the telescope . Celestron
provides a T-ring for both Nikon (#93402) and Canon (#93419) .
Tele-Extender, Deluxe (#93643) – The tele-extender is a hollow tube
that allows you to attach a camera to the telescope when the eyepiece
is installed. This accessory is used for eyepiece projection photography
which allows you to capture very high power views of the Sun, Moon and
planets on film. The tele-extender fits over the eyepiece onto the visual
back . This tele-extender works with eyepieces that have large housings,
like the Celestron Ultima series .
HD Pro Wedge (#93664) – Celestron’s HD Pro Wedge allows you
to tilt the telescope so that its polar axis is parallel to the earth’s
axis of rotation. Ideal for using
your CPC DeluxeHD for guided
astrophotography . The Pro Wedge is
designed to support our fork mounted
telescopes up to 11” . The HD Pro Wedge
provides a heavy duty, stable platform
that is perfect for astroimaging and
guarantees minimal vibration . A low
latitude range of 0-90 degrees makes
this wedge functional for use at
the equator .
