SkyWatcher ED Black Diamond ED100 PRO HEQ5 GOTO Refractor Telescope SkyWatcher ED Black Diamond ED100 PRO HEQ5 GOTO

The apochromatic ED refractor tubes of theBLACK DIAMONDseries from SKYWATCHER represent a range of refracting astronomical telescopes with a fairly well-corrected field and highly corrected chromatic aberration. Their low dispersion ED optics allow light to refract through the lens so that the light beam does not scatter much (does not open up) and therefore the image definition is greatly increased. SKYWATCHER BLACK DIAMOND refractors are constructed with a two-element air-spaced objective lens. The second lens element is constructed with the high quality fluorinated glass FPL-53 (O'HARA version).

The ED optics of the BLACK DIAMOND refractor telescopes are made of SCHOTT glass. This combines the efforts of two market leaders, Synta as a manufacturer of astronomical telescopes and SCHOTT as the world's leading manufacturer of the highest quality optical glass.

SkyWatcher offers a simple solution for users who would like to be able to attach their small telescope to a computerized mount without having to carry the weight of a NEQ6 or AZEQ6 mount. The HEQ5 Pro mount uses the same GOTO system as the EQ6-R and NEQ6 PRO mounts, the SynScan system. It allows you to locate a specific object and even allows you to travel from one object to another along a Tour by simply pressing a button.

Key features:

• • • • • Aiming accuracy up to 1 arcminute. Improved accuracy by means of collimation error compensation software.
        • Stepper motors with a step angle of 1.8º and 32 teeth.
        • GOTO speed up to 3.4º/second (at 800x).
        • Guiding speed selectable between 0.25x, 0.5x, 0.75x and 1x.
        • Object database including complete Messier, NGC and IC catalogs.
        • Periodic error correction.
        • PC compatibility
        • Control knob, SYNSCAN EQ included.

SKYWATCHER telescopes supplied with a German equatorial mount with integrated SynScan system are high quality observing platforms with well thought-out mechanics and electronics.

The main features of the GOTO systems are summarized below:

Motors, crowns and bearings:

The SKYWATCHER mounts of the SynScan series use DC stepper motors with high torque capacity and microstepping control technology for maximum precision. Bronze crown and worm gear system for precision mechanical incremental movement minimizing gear backlash.

Tracking speeds and modes

The versatility of the SynScan system allows various search and guidance speeds to be selected. The tracking modes are: Lunar, Solar and Sidereal. The mount is compatible with use in both the Northern and Southern hemispheres.

Database

The SynScan computer includes a database of over 40,000 objects in memory. The library includes objects for advanced studies, following the existing catalog system: NGC, IC, Caldwell, Messier and other lists plus 25 user-definable objects (comets, asteroids, etc).

Astrophotography

Astrophotography enthusiasts will greatly appreciate the presence of the AUTO-GUIDER port that allows autoguider functions to be performed through a PC. The SynScan firmware includes the SynScangramming algorithm for periodic error correction (this error is natural and inherent to all corona-bisenfin systems). In addition, this algorithm can be complemented with the Backlash compensation function (technical term to describe gear backlash) for both AR and DEC. In this way it is possible to have uniform GOTO's and tracking.
