Losmandy Precision Equatorial
Mounts. (Also see G-11 and HGM
titan) 
Made in the U.S.A by Hollywood General Machining, the German equatorial mountings designed by Scott Losmandy are recognised the world over as one of the most precise, rigid and yet affordable telescope mountings commercially available. Losmandy produce the portable G-8, heavy duty G-11 and observatory class HGM Titan.

summary)
The Losmandy range is designed for exacting astro-photographic, CCD imaging and visual users in both the field or at a permanent installation.
The G-8 design is very rigid yet light weight and incorporates features simply not found in competing equatorial mounts. All structural parts are fully machined from aircraft grade aluminum or stainless steel. Aluminum parts are anodized: a process, which significantly hardens the metal surface and protects it against corrosion. Utilizing the latest Computer Numeric Control (CNC) technology tolerances to within a few thousands of an inch are rigidly maintained across the entire assembly: guaranteeing smooth, precise and dependable performance for many years to come.
Being all-machined, the G-8 is extremely rigid. Add large diameter shafts plus design features such as; polar altitude lock, precision gears and bearings to create a mount easily capable of supporting payloads of up to 15kg, yet still retain excellent field portability.
The drive assembly uses dependable, high-torque stepper motors, each driving a super hard, tempered stainless steel worm gear. Unlike the turned gears used in less capable mounts, each worm gear is precision ground to tolerances of a few ten thousands of an inch. The result is consistent tracking accuracy of less than 20 arc seconds without the aid of periodic error correction electronics (also built into every G-8 mount).
Unique to every Losmandy mount is their precision dovetail and saddle system. A single doveplate can be attached to almost any telescope, which can then be attached to the mount saddle in seconds. Perfect balance of the system can then be easily achieved by simply sliding the telescope along the saddle.
Completing the mechanical system is Losmandy’s G-8 field tripod: a semi-pier head, coupled to thick walled, large section aluminium legs, plus a spreader bar giving the field system excellent rigidity and dampening characteristics. Vibrations literally damp out within fractions of a second.
Electronically, the G-8 has features tailored for the advanced astro-imager. Three guiding rates, plus four slewing rates. Quartz locked tracking at Sidereal, Solar, Lunar and King rates is also provided. The periodic error correction circuit is unique as it does not alter the set tracking rate, nor slowly drift out of phase. Tracking with the PEC engaged is virtually error free. Any residual mechanical backlash in the declination drive can also be easily removed by the built in TVC feature, giving the user precise and instant drive correction response. An autoguider jack allows trouble free interfacing with currently available autoguiders. A compact hand paddle allows drive corrections to be applied in the correct sense, no matter what the optical configuration or telescope orientation through reversible R.A and Declination switches.
Alternatively, the G-8 can be fitted with the Gemini computerised GOTO system. This can be fitted to a new mount, or retrofitted at a later time.
The Losmandy G-8 offers high precision, high payload, excellent stability, innovative compact design and jewel like finish which combine to make it the ideal foundation for a superb astro-imaging system.
