Orion HDX110 EQ-G GoTo Equatorial Mount - Head Only

Orion HDX110 EQ-G GoTo Equatorial Mount

The Orion HDX110 EQ-G equatorial mount offers ultra high precision and a solid frame capable of carrying up to 110 pounds in equipment while still maintaining excellent tracking. +/-3 arcsecond tracking without PEC (Periodic Error Correction). The HDX 110 from Orion provides stability and accuracy for demanding imaging and observing setups. This model is the head only with counterweight shaft and cables. It does not include a tripod, case, pier and counterweights.

Featuring robust, observatory-grade electronics which includes high resolution, micro-stepped stepper motors and patented dual-encoder technology which allows both automated operation and manual slewing, without losing the initial GoTo alignment. The alignment is so well maintained that once it has been successfully completed, you can loosen the RA and DEC clutches to reposition the mount with telescope attached and you will still be accurately aligned upon relocking the clutches!

Utilizing Orion's SynScan GoTo controller, the Orion HDX110 can be pointed to anyone of the 42,000 objects in the database with ease. It also allows for a highly accurate polar alignment routine that doesn't require a polar aligning scope - or a view of Polaris. This smart mount also offers permanent periodic error correction (PPEC) to improve on the already excellent PEC. The correction is saved from session to session.

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

Ask a Question
  • Does the mount head (the kit w/o tripod) include a counterweight?

    The Orion HDX110 head only does not come with a counterweight.

  • Is the imaging capacity of this mount 55 lbs?

    Hi Mike, The weight capacity of the HDX mount is 110 lbs. For imaging you would want to keep it at 50-60% of capacity which makes it around 55-65 lbs.
