Sky-Watcher - HEQ5 Mount GoTo Equatorial Mount - S30400

Sky-Watcher SynScan mounts have been designed for use by novices and experts alike. These mounts provide extremely high precision tracking and have built in autoguider ports. This heavy-duty HEQ5 Pro mount is a smaller version of the sturdy EQ6 Pro mount. It is specially designed for observers who need the steadiness of the EQ6 Pro mount but finds the EQ6 Pro mount too physically demanding.

For novice users the user-friendly menu allows automatic slewing to 42900+ objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The SynScan Hand Control also has the ability to connect to a computer via an RS-232 cable. Once the connection has been established between the computer and SynScan Hand Control, many commercially available planetarium software programs can be used to control the HEQ5 PRO Mounts, They also come with features that advanced astronomers can appreciate.

Sky-Watcher - Esprit 80mm ED Triplet APO Refractor - S11400

The Sky-Watcher Esprit 80mm ED Triplet Apochromatic Refractor Optical Tube Assembly is geared towards serious astrophotographers who want absolutely no compromise in the clarity of their images and exposures while being reasonably priced for a telescope of its quality. The clarity and excellent light transmission and virtually non existent chromatic aberration or false color of the Esprit 80ED is mainly credited to the apochromatic three element design, ED glass and Sky-Watcher's Metallic High Transmission Coatings (MHTC for short).

The Sky-Watcher Esprit 80ED comes with a dual speed Rack and Pinion Helinear track focuser which helps faciliate smooth and accurate focusing with no image shift, a major crucial factor in high quality exposures and a flawless visual session. The focuser can be rotated as well to correspond with how the imager is taking their exposure frames.

Other included items are a 2 element field corrector, 8x50 right angle finderscope, 2" diagonal, M48 camera adapter, mounting hardware and padded case.

  • Sky-Watcher Esprit 80ED Triplet APO Refractor OTA is an excellent choice for astroimagers who want the best optics possible for sharp exposures!
  • Chromatic aberration and false color is virtually eliminated, thanks to the ED glass, APO design and MHTC coatings.
  • The included Dual Speed RP Helinear focuser provides smooth and accurate focusing, a major plus for both imagers and visual observers.
  • The optical tube is made from rolled steel with a white glossy finish.
  • The Esprit 80ED comes with a field flattener, V style mounting foot, 8x50 right angle finderscope, M48 camera adapter, 2" dielectric diagonal, and padded hard case.
