About the Losmandy G11 Equatorial Mount

Scott Losmandy is the designer of the world-famous G-11 mount and tripod that works with most popular-sized telescopes for the serious astronomer. A lifelong amateur astronomer, designer, and machinist, Losmandy understands the functional requirements of demanding astrophotography and astronomy. His designs are characterized by precision all-machined parts in aluminum and stainless steel that are not only beautiful but built with a strength that will handle heavy payloads for a lifetime of constant use. Mr. Losmandy has graciously allowed us to buy these mounts and add the new Explore Scientific PMC-Eight GoTo system with its precision stepper motors.

The PMC-Eight Electronics are unique and special as well, with extremely robust designs. They include a Multi-Processor Micro-controller with 8 CPUs (thus the name) that run independently and are completely deterministic in their behavior. Within this multi-processor system is a 64 Kbyte EEPROM Non-Volatile Memory bank; a Wireless Ethernet 10/100 with full IP function which permits operation from anywhere using a browser, ASCOM, or APP over the web or serial port and Non-Volatile Memory used to store user selected parameters. This system is all controlled from a Windows app for PC, tablet, or phone with a full graphical user interface called ExploreStars - the first application from the OpenGOTO Community.

Based on the Russell W. Porter Slip-Ring design, this German Equatorial mount is manufactured with all-machined aluminum and stainless steel and finished in black with a durable hard anodize. Removable stainless steel 1-1/4-inch diameter weight shaft w/safety knob. A 21-lb counterweight is standard equipment, and optional 7 lb and 11 lb counterweights are available. The G-11 is rated for 100 lbs total capacity (instruments and counterweights combined).

The Losmandy G-11 mount is moved by newly installed high-resolution 09° 400 count stepper motors with a micro stepping controller that makes the motor work at 12,800 steps per revolution with drive rates accurate to a few arc-seconds per day.

The system uses a classic four-button pattern for guiding, centering, moving and slewing on the touch screen of your tablet or phone. Selectable and User Enter-able GoTo, Slewing, Centering and Guiding Rate. Your standard 1-star, 2-star and 3-star alignment functions. The system includes a database of more than 70,000 objects, but the interface presents these objects with impressive graphics that are beautiful yet user-friendly. Along with Sidereal, King, Lunar, Solar and user-defined tracking rates, the system includes a synchronize function, search function and coordinate input. There’s also a custom mount support option if you use the enterable stepper count scaling and Polar Axis Correction.

Polar alignment adjustments are precise and smooth. For initial polar alignment setup, the G-11 has two bubble levels and the mount's latitude scale is laser etched in 2-degree increments. The equatorial head is supported by the Losmandy HD Folding Tripod with its massive 3-inch diameter, continuously adjustable legs for precise leveling. The mount's 1.25-inch stainless steel polar axis is hollowed to allow through the polar axis sighting of the Northern or Southern Celestial pole, and an optional Polar Scope, to help make precision polar alignments quick and easy. The unique fully locking tangent arm design for altitude adjustment for aligning to the celestial pole is from 6-68 degrees latitude and sports a large easy-to-adjust aluminum knob. The single knob azimuth control is bi-directional with +/- 8.5 degrees adjustment.

The ExploreStars App

Our ExploreStars app has basic functions found in other GOTO systems, with an important exception. The app and the command language driving the PMC-Eight is open source. This means that anyone can modify our software or create their own software through our Software Developers Kit (SDK) and you can download your modified software onto our electronics.

Create a Messier challenge, a selectable list of objects you want to photograph and program that information into the software, and share it with the community of astronomers that are using this software. We plan to offer a prize with a contest periodically for the best software package written.
