For quick visual astronomy and daylight terrestrial studies, the Sky Watcher Startravel 102 Refractor Astronomy Telescope with AZ5 Mount 10261 is the perfect No Fuss, Grab-and-Go Telescope!
With the correct safety filtering, the Sky Watcher Startravel 102 is a well-proven performer for 'Rich-Field' views of comets, star fields, star clusters, nebulae, brilliant galaxies & planets, the Moon, and the Sun.
The telescope can be used for terrestrial observing because the included erect image diagonal produces an image that is upright and fully adjusted.
The AZ5 Deluxe Alt-Azimuth mount's attractive, well-engineered, and simple design provide it outstanding stability and accurate control on both the horizontal (azimuth) and vertical (altitude) axes.
102mm achromatic refractor
Deluxe Alt-Azimuth Mount AZ5
This Sky-Watcher 102mm (4") f/4.9 telescope has two air-spaced, completely multi-coated, achromatic elements and may produce fascinating 'rich field' astronomical views. 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 to its clear images and affordable pricing. Similar to the well-known 80mm f/5 refractor, this bigger aperture type accepts 2" diagonals for amazing wide field views and has more light gathering power at the same focal ratio with less weight and chromatic aberration.
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. Being a refractor, it is quick and simple to set up, and the enclosed optics, which require no maintenance, are fully collimated when they leave the manufacturer.
"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 pictures of nature and lunar and solar eclipses. Longer exposure astrophotography requires a stable equatorial platform and a guiding system. An suitable T-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.
