• New "All-star" Polar alignment uses any bright star for a quick and accurate Polar alignment.
• Software Features include: Mount Calibration, Database Filter Limits, Hibernate, five Alignment Procedures.
• Flash upgradeable hand control software and motor control units for downloading product updates over the Internet.
• Custom database lists of all the most famous deep-sky objects by name and catalog number: the most beautiful double, triple and quadruple stars; variable star; solar systems; objects and asterisms.
• Permanent programmable periodic error correction (PEC) - corrects for periodic tracking errors inherent to all worm drives.
• Drive Motors - Low Cog DC Servo motor with integrated optical encoders offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking.
• Internal Cable wiring for trouble-free setup and transportation.
• Designated six-pin RJ-12 modular jack, ST-4 compatible guide port.
