The Sky Watcher Startravel 120 Refractor Astronomy Telescope with AZ3 Mount 10736 is a two-element, air-spaced achromatic refractor, that is a well proven performer for ‘Rich-Field’ views. Comes with an easy to use AZ3 Alt-Azimuth mount.

The Sky Watcher Startravel 120 Refractor Astronomy Telescope with AZ3 Mount 10736 is a two-element, air-spaced achromatic refractor, that are well-proven performers for "Rich-Field" views of comets, star fields, star clusters, nebulae, brighter galaxies & planets, the Moon and the Sun (with proper safety filtering! ), as well as giving excellent daytime terrestrial views. These short-tube, wide-field telescopes work well as fixed aperture lenses for both planetary and astronomical photography. They are useful for taking pictures of nature and lunar and solar eclipses due to their "fast" focal ratios.

Ideal for Deep-Sky Astronomical Use as well as Daytime Terrestrial Observations

The AZ3 Alt-Azimuth mount's slow motion cables, which are simple to use and intuitive, offer great stability and accurate control on both the horizontal (azimuth) and vertical (altitude) axes.

Air-Spaced Two-Element Achromatic Refractors
A standard single lens directs light of various wavelengths to various focal points.
Air-spaced two-element lenses, which minimise chromatic aberration more than conventional doublet lenses, are used in the construction of all Sky-Watcher Refractors.

This Sky-Watcher Startravel 120 is a 120mm (4") f/5 telescope and is an intriguing "rich field" achromatic refractor with two elements, air spacing, and completely multi-coated objectives. Excellent views of star fields, clusters, nebulae, galaxies, planets, the Moon, and (with the right filtering or through projection) the Sun can be obtained. When set up on a camera tripod or an alt-azimuth mount, it also makes a great terrestrial telescope. It makes a superb "first telescope" for beginners and a fantastic travel telescope for seasoned observers because of its clear images and affordable pricing.

This wider aperture variant accepts 2" diagonals for amazing wide field views and has more light gathering power at the same focal ratio with less weight and chromatic distortion. With a compressed length of about 50 cm (21.7") and a weight of around 3 kg (6.5 lbs), the optical tube assembly is easily carried.

The Startravel 120 is quick and simple to set up as a refractor, and the enclosed optics, which require little maintenance, are factory-collimated. "Tube mounting rings" are included with the optical tube assembly. These may be opened on a hinge to make installing the optical tube simple, and the locks can be released while in use to allow rotation and balance of the optical tube. With the proper mounting plate, it is quick and easy to mount the telescope on an equatorial or alt-azimuth mount. Additionally, this telescope functions well as a 510mm fixed aperture lens for both terrestrial and astronomical photography.

With today's high-speed films and the "fast" f/5 focal ratio, you may take stunning photos of nature and lunar and solar eclipses. Longer exposure astrophotography requires a stable equatorial platform and a guiding system. A suitable T2-adapter may be directly attached to the eyepiece holder's T-mount thread, and an optional extension tube provides closer focussing for taking pictures of the ground.
