This is a standalone computer for an NGC-MAX installation, including a 15-pin RS232 serial cable. It does NOT include the encoders or other hardware. This was taken out of our club's storage unit. It appears to function properly, however the purchase is considered "AS-IS".
Markings on the unit include "NGC-MAX", "Jim's Mobile Industries", "Product of Celestron International," and "Made in USA."
Requires one 9V battery (New battery included.).
About the NGC-MAX:
The NGC-MAX tells you where your telescope is pointed and how to point it to a specific target. This requires encoders (not included) that are attached to the telescope mount. It is also able to tell you what object you're pointed at. This system is compatible with most types of telescopes, such as Dobsonians and German Equatorials.
