Digital Setting Circles: Advanced Astro
Master®
Computerize your telescope! This pointing
system contains a database of over 10,000
objects. Once aligned, it will guide you to any
one of these objects. Included are the entire
RNGC catalog, the Messier catalog, IC catalog
(selected objects), major planets, over 241
interesting double and multiple stars, and a user
definable catalog of 25 objects!
Can be used with or without an equatorial
mount, eliminating the need to polar align, enter longitude or time. Gives a
scrolling description of each object, directs you from object to object, and
immediately aligns on the object currently viewed. The 16 character LED
readout provides object coordinates, magnitude, type, common name, constel-
lation and additional description. Operates on a 9 volt battery (included),
weighs 6 ounces and is easy to install.
It contains a RS-232 serial interface to PC programs. The module is sold
separately and installation kits are available for various telescopes. The kit
contains two optical encoders, cables and all necessary brackets and hardware.
Made in USA.
