Item #  10044

Discover a new level of precision performance with the Orion HDX110 EQ-G GoTo Equatorial Mount. Offering exceptionally low, typically +/-3 arcsecond tracking without correction (PEC) and a massive 110-lb. instrument capacity, the big Orion HDX110 EQ-G Mount offers demanding observers and astrophotographers unprecedented accuracy and performance for the price. This model includes the HDX110 Mount head, GoTo Hand Controller, counterweight shaft and cables. Does not include tripod pier.

This heavy-duty head-turner of a telescope mount features robust, state-of-the-art electronics, including high-resolution, micro-stepped stepper motors and patented dual-encoder technology that allows both automated GoTo operation and manual slewing, without losing the GoTo alignment. In fact, once a successful alignment has been completed, you can loosen the RA and DEC clutches and manually reposition the mount and attached telescope while still maintaining the GoTo accuracy once the clutches are relocked.

The time-tested SynScan GoTo controller houses a 42,000-object database, and offers a highly accurate, iterative polar alignment routine that doesn't require a polar alignment scope, or even a view of the star Polaris (an optional Orion Polar Alignment  Finder Scope for HDX110 EQ-G is available for those who prefer using a dedicated alignment scope). Permanent periodic error correction (PPEC) can be employed to improve the already impressive native periodic error even further, and the PEC is saved for future observing/imaging sessions (hence, "permanent").

The HDX110 Mount's EQ head features 8.6" (219.5mm) Right Ascension (RA) and Declination (Dec) worm wheels with 435 gear teeth and a thick RA and Dec shaft diameter of 55mm. It's equipped with an autoguider port, buttery smooth latitude jackscrew with a 10-65 range, precise azimuth adjustment knobs (+/- 10 range from center), SNAP port (for DSLR shutter control), and ON/OFF switch. The mount head itself weighs 55 lbs. - yes, that's hefty - but it's equipped with two large handles that make it easy to lift. The 1.25"-diameter stainless steel counterweight shaft threads securely into the mount head. The saddle is a wide, "Losmandy-style" clamp plate with three locking hand knobs.

This model of the HDX110 includes the equatorial mount head, counterweight shaft, GoTo hand controller and cables. Counterweights are sold separately. Tripod pier not included. The HDX110 instruction manual includes schematic plans of the mount's baseplate with dimensions for those interested in attaching the HDX110 telescope mount to a permanent pier or a preferred tripod.

An externally mounted polar scope for the HDX110 is optionally available (sold separately). The Orion HDX110 EQ-G GoTo Mount requires a 12V DC, 4A power supply or field-battery for motorized operation. A 12V DC power cable with auto-lighter plug and threaded connector to the mount is included.
