Celestron CR-150 HD instruction manual Motor Drive System - #93518, Optional Accessories

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.
