HEQ5 PRO

Sky-Watcher Pro 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 find the EQ6 Pro mount too physically demanding.

For novice users the user-friendly menu allows automatic slewing to over 13,400 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 a 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:

Diffraction-limited secondary mirror support
Paraboloidal (parabolic) primary mirror
200mm primary mirror gives magnificent images of deep-sky objects. 78% more light than 150mm, 137% more light than 130mm
Huge 9x50 achromatic finder scope reveals objects that elude smaller finder scopes
1.5" Steel tripod legs for maximum stability
Perfect instrument for serious amateur

Four-arm, secondary-mirror bracket with fine supports

The Sky-Watcher paraboloidal (parabolic) mirror reflectors and all Dobsonian models feature a four-arm, secondary-mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss

Reflecting telescopes with spherical mirrors often have a defect called "spherical aberration." Light rays from the perimeter of the spherical mirror do not focus to the same point as rays from the centre, resulting in images with less sharpness and detail. This problem is not critical for smaller Newtonians, and other reflecting telescopes with focal ratios of f/9 or higher, where the aberration is minimal. However, it becomes more noticeable in larger Newtonians and other reflectors having ratios of f/8 or lower.

 

For larger Newtonians, such as Sky-Watcher the spherical surface of the mirror is altered during polishing to bring the light rays onto a common focal plane. By "parabolising" the mirror, the images become sharp and detailed, and free of spherical aberration effects. Sky-Watcher parabolic mirror reflectors also feature a four-arm, secondary mirror bracket with fine supports to reduce diffraction spikes.

Accurate parabolising, although more difficult and time-consuming, is essential for large Newtonians. If you have opted for a telescope of lower f/ratio or with an aperture of 150mm or more, it is important to look for "parabolic mirror" or "paraboloidal mirror" in the specifications.
