| The industry-standard Losmandy G-11 is a rock solid visual and photographic tracking equatorial mount that can hold an instrument payload of up to 60 pounds. While not the most portable mount in the world, weighing in at 92 pounds with its 21 lb counterweight, it can generally be taken down and set up rather easily by one person, as the heaviest single component weighs only 36 lbs. This mount has excellent drive smoothness and accuracy, plus programmable periodic error correction, and is nicely suited for astrophotography. EQUATORIAL HEAD SPECIFICATIONS - Made of machined aluminum and stainless steel, black anodized.
- All stainless steel hardware.
- One 3.750" diameter needle thrust bearing.
- One 2.000" diameter needle thrust bearing.

- Single knob azimuth control, bi-directional +/- 8.5°.
- 5.000" diameter laser engraved setting circles: right ascension divided in one hour increments, with 4 minute tic marks and a vernier reading to 1 minute; declination divided in 10° increments, with 1° tic marks and a vernier reading to 0.1°. Right ascension circle engraved for both Northern and Southern Hemisphere use.
- Porter slip ring design.
- 160 oz/in stepper motor, 0.5 arc sec. steps.
