This is a only slightly used Argo Navis - it is like new and works great - I've upgraded to a Gemini goto so I don't need it anymore. Asking $300. I take PayPal and I pay the 3%. What follows is the manufactures sales pitch:
"The Argo Navis is FULLY field upgradeable so it will ALWAYS be accurate, always be up to date, and always be there to serve your needs. With features like:
-29,000 Objects with size, mag, constellation, Morph, Surface
Brightness, Atlas, even if it is above the horizon!
-1500+ USER objects WITH Text
-Comets, asteroids, even satellites
-FAST real time IDENTIFY mode...
-TOUR mode that is a joy to use, and a powerful tool for the serious observer. Criteria: type, size, constellation, even radius to tour
-Common names of objects - find the Whirlpool (not NGC5194)
-Most accurate DSC going: planets to the second not day, refraction correction, precession (so it will be accurate FIVE years from now!), mount correction... it even calculates the accuracy of your alignment and corrects for it!
-Encoder test mode
-Dual serial port - LX200, Tangent, Sky Commander, ServoCAT compatible
-Battery backed real time clock (and it has a TIMER)
-DOBS, EQs, Platform compatible
-FAST encoder sample rate - never have a problem overrunning encoders (even if 8192's or higher!).
-Compatible with standard encoders and cables used today.
-compatible with the ServoCAT Track and GOTO system including GOTOs from your PC planetarium program (if desired). "
