For optimal performance in astronomical observing
that involves setting circles or motorized tracking,
Celestron’s telescopes with a fork mount and motor
drive must be mounted on an Equatorial Wedge. The
wedge allows you to tilt the telescope so that its polar
axis (R.A. axis) is parallel to the earth’s axis.
The angle of tilt will depend on your latitude when
the telescope is level. The angle between the horizon
level and the polar axis will equal your latitude when
the telescope’s axis is parallel with that of the earth’s.
Once properly mounted and adjusted on the wedge,
the telescope is said to be equatorially mounted and
its setting circles can be used to locate deep-sky
objects.
C5 Wedge — #93654
Is standard with the C5 + telescope. An optional upgrade for the C8 telescope is to use
the C5 Wedge, which allows the C8 to be used more easily as a tabletop telescope. The
C5 Wedge comes with height adjustment screws and
a bubble level, and has a latitude range of 0° to 90°.
Standard C8 Wedge — #93656
Is Standard with the Celestar 8 Deluxe telescope. It
can be used as an upgrade for the basic Celestar 8
telescope when used with an adjustable tripod or as a
tabletop telescope.
Deluxe Latitude Adjuster – #93528
Raise and lower the tilt plate of the C8 wedge
(#93656) with fine precision, using Celestron’s Deluxe
Latitude Adjuster. Used during the polar alignment
process, this adjuster is a real time saver. Especially convenient if you observe from a
variety of different sites, which necessitates readjusting your polar alignment for each
location.
The Deluxe Latitude Adjuster consists primarily of a heavy-duty latitude adjustment bar
with a large central adjustment knob. Also included are bolts with oversized knobs for
attaching the telescope to the wedge, and for locking
the tilt plate to the side of the wedge.
Heavy-Duty Wedge — #93655
For Celestron‘s C8 and C11 telescopes. It is available
for the more serious observer. It is standard with the
Ultima 9
1 /
4
and Ultima 11 telescopes. It is sold as an
option for Ultima 2000 — 8" telescopes. It can also be
used as an upgrade for the standard C8 telescopes. It
increases the rigidity of the telescope while giving a 0°
to 90° range of operation. An upgrade kit with a
deluxe latitude adjuster and azimuth controls for easy
polar alignment is available (#93662).
