Motor Drive System - #93518
By adding the MDCG-5 Drive System to your mount, you add the capacity to
automatically track objects in the sky, a convenience you’ll be sure to enjoy
during long viewing or astrophotography sessions, when manual tracking can
become tiring. Furthermore, the Drive System will enhance high-power visual
observing. It attaches to the R.A. (east/west) drive axis of your CG-5 Mount
and will drive the telescope at the normal sidereal rate as well as allowing you
to guide at 2x and 4x sidereal. Power is supplied via a DC battery pack.
Planisphere (93720) - A simple and inexpensive tool for all levels of observers,
from naked eye viewers to users of highly sophisticated telescopes. The
Celestron Planisphere makes it easy to locate stars for observing and is a
great planet finder as well. A map of the night sky, oriented by month and day,
rotates within a depiction of the 24 hours of the day, to display exactly which
stars and planets will be visible at any given time. Ingeniously simple to use,
yet quite effective. Made of durable materials and coated for added
protection. Celestron Planispheres come in three different models, to match
the latitude from which you’re observing:
For 20 ° to 40 ° of latitude 93720-30
For 30 ° to 50 ° of latitude 93720-40
For 40 ° to 60 ° of latitude 93720-50
Polarizing Filter Set (#93608) - The polarizing filter set limits the transmis-
sion of light to a specific plane, thus increasing contrast between various
objects. This is used primarily for terrestrial, lunar and planetary observing.
Polar Axis Finderscope (#94221) - This useful accessory speeds accurate
polar alignment by providing a means of visually aligning your German equato-
rial mount with Polaris and true north. The finderscope has an eyepiece with
etched reticle for quick polar alignment.
Sky Maps (#93722) - Celestron Sky Maps are the ideal teaching guide for learning the night sky. You wouldn’t
set off on a road trip without a road map, and you don’t need to try to navigate the night sky without a map
either. Even if you already know your way around the major
constellations, these maps can help you locate all kinds of
fascinating objects.
T-Ring - The T-Ring couples your 35mm SLR camera body to
the T-Adapter, Radial Guider, or Tele-extender. This accessory
is mandatory if you want to do photography through the
telescope. Each camera make (i.e., Minolta, Nikon, Pentax,
etc.) has its own unique mount and therefore, its own T-Ring.
Celestron has 8 different models for 35mm cameras.
