Explore Scientific Losmandy G-11 Equatorial Mount w/ PMC-Eight GoTo System - ES-G11PMC8-00

Introducing the Explore Scientific Losmandy G-11 Equatorial Mount with the PMC-Eight GoTo System.

Designed by Explore Scientific's engineers, this innovative mount features a robust eight-processor electronics board, setting a new standard in precision motion control for telescopes.

What sets this system apart is its commitment to open-source technology, allowing the astronomical community to create tailored GoTo experiences and platforms for both casual observation and research.

This high-end equatorial mount offers both hardwired and wireless connectivity to ASCOM-compatible software, making it incredibly versatile.

For those without such software, Explore Scientific provides the user-friendly ExploreStars control graphical interface, available as a free download from various app stores, including Microsoft, Google Play, and iTunes (for Windows 8.1, 10, Android, Amazon Fire, and Apple tablets, which must be purchased separately).

The underlying Losmandy G-11 mount has undergone modifications to enhance precision and performance. Stepper motors have replaced standard servo motors for finer control, achieving a motor rate accuracy of 0.01 arc seconds per second.

Helical couplers have been added to ensure secure worm and motor connections in both the RA and DEC axes, increasing reliability.

The inclusion of the Losmandy RA extension further extends tracking capabilities and aids in transportation with its convenient modular design.

At the core of the PMC-Eight GoTo controller is an eight-processor microcontroller with advanced features like wireless Ethernet with full IP function, enabling remote access from anywhere.

Explore Scientific has embraced an open-source philosophy, offering documentation and example software for creative applications within the OpenGoTo® Community.

Their ASCOM-compatible wireless driver is among the few available and offers complete open-source code for customization.

With a 60-pound payload capacity and compatibility with various ASCOM software packages, the Explore Scientific Losmandy G-11 with PMC-Eight is an ideal choice for dedicated astronomers.

Its precision and adaptability empower advanced amateur astronomers to develop their applications. Controlled by ExploreStars, it's also a crowd-pleaser at outreach events and star parties.
