The Sky-Watcher 70/900 EQ1 is an Achromatic Refractor that uses a 2-element fully multi-coated lens. With 70mm aperture, this telescope has significant 36% more light gathering capacity than 60mm telescope, provides enough light to bring you clear, crisp images of the popular celestial bodies and brighter deep sky objects.
With maximum practical magnification of 140x, this Sky-Watcher Telescope will reveal details in Saturn’s rings and Jupiter’s bands, whilst the cratered landscape of the Moon is a delight to observe over different phases.
The Refractor Advantage
Since a refractor does not use mirrors to view objects, you get a generally sharper image. Images are also displayed without the secondary mirror shadow, making it suitable for terrestrial viewing when used with a 45° erecting image diagonal or an erecting tube.
Equatorial Mount Features
The EQ1 is a lightweight equatorial mount, able to compensate for Earth’s rotation by moving along only one axis. That is a great advantage for high resolution observation as it is only necessary to turn a single knob whilst tracking an object across the sky. The optional tracking motor can be easily attached to the right ascension axis, allowing comfortable observation without the work of manual tracking.
Aligning an equatorial mount is an easy operation that can be completed in a few minutes. Once the tripod is levelled and the mount is orientated south, incline the mount at the same angle of your local latitude. For example, if you are in Sydney (latitude 33° South), adjust the mount inclination to 33° above the horizon using the scale on the EQ1 mount.
