About the Celestron HD Pro Wedge

Eric A.

Celestron's HD Pro Wedge is perfect for astrophotographers. Stars rotate around the celestial pole, so if you track them with an altazimuth mount the stars will rotate during your exposures, causing them to become blurry over a long exposure. This wedge allows your motorized mount to move more accurately in just a single direction, so you can take clear, steady photos of the night sky. It also offers a latitude range from 0-90°, so it can be used at the equator. Rugged, solid construction keeps vibrations from spoiling your photos.

Product highlights:

  • stable platform is perfect for astro imaging and guarantees minimal vibration
  • designed to support fork mounted Schmidt Cassegrain Telescopes up to 11"
  • low latitude range of 0-90 degrees allows use at the equator
  • built-in altitude/azimuth adjustment controls with oversized knobs for easy polar alignment
  • hand control holder
  • tilt plate allows for easier mounting of the telescope
  • 14mm diameter latitude adjustment screw to add strength and stability while supplying less vibration and easier rotation with a heavy telescope
  • warranty: 2 years
  • MFR # 93664

Features

Overview: The Celestron HD Pro Wedge is a heavy duty platform for mounting between fork-mounted CPC telescopes and the tripod. This wedge allows you to tilt the telescope's axis of rotation so the telescope (with its built-in motor drive) can track the stars as they move in an arc around the celestial pole. The HD Pro Wedge provides a stable platform, making it easier to rotate a heavy telescope. It virtually eliminates vibration for better astro-imaging. The wedge comes with mounting hardware and an assortment of Allen wrenches for attaching and adjusting the device.

Latitude Adjustment Screw: The HD Pro Wedge has a large 14mm diameter Latitude Adjustment Screw with an oversized (2.75" diameter) knob for rotating the telescope to the latitude you desire. Having a large diameter adjustment screw adds strength and stability, resists flexing or bending, and prevents vibrations when adjusting a large, heavy telescope.

Latitude Range: The wedge can be configured for two different ranges of latitude. It comes configured for latitudes of 40°-90°. If you are located at a latitude of 40° or below, you'll need to adjust the latitude plates on the side of the wedge. The low range of 0° to 50° can be used all the way south to the equator.

Note: The continental United States is essentially equally divided by the 40° latitude parallel. The southern half of the country (roughly 25° to 40°) will need to adjust the latitude plates and use the 0° to 50° range. Because the ranges overlap between 40° and 50°, the northern half of the country can use either range. Alaska is located between 60° and 70°, while Hawaii is located near the 20° parallel.

Altitude/Azumuth Controls: To assist you with polar alignment, the HD Pro Wedge includes altitude/azumuth controls with 2" diameter knobs. After loosening the wedge's azimuth plate screws, you can make the final adjustments in azimuth to achieve polar alignment.

Installation: The HD Pro Wedge attaches to the HD tripod using the three supplied socket head bolts. There are two attachment configurations for maximum stability, depending upon whether you're in a lower or higher latitude. Once the wedge is mounted to the tripod, the telescope is mounted to the tilt plate of the wedge.

Hand Control Holder: The CPC telescopes include a computerized hand control, which typically would attach to one of the tripod legs. The HD Pro Wedge, which mounts between the tripod and the telescope, has a built-in holder for the hand control, which positions the hand control in a more convenient and secure place.
