Orion HDX110 EQ-G GoTo Equatorial Mount with Tripod Pier

Take your stargazing sessions and astrophotographic pursuits to the next level of precision with the Orion HDX110 EQ-G GoTo Equatorial Mount with Tripod Pier. 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 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 10ø-65ø range, precise azimuth adjustment knobs (+/- 10ø 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 on and off the included tripod pier. 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. Two 22.3-lb. (10kg) counterweights are included.

The HDX110 EQ-G Mount's combination tripod and pier provides solid, unflinching support for the EQ head, which conveniently attaches with a single hand knob on the 5.5"-diameter pier. The substantial 2.4"-diameter steel legs fold inward for easy transport. Three heavy duty leveling pads are included, which can be placed under the tripod feet to level the mount on almost any terrain. The pier adjusts in height to place the EQ head's dovetail saddle 46" to 58" above ground (excluding leveling pads). The tripod-pier weighs 64 lbs.

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.
