This Sky-watcher Startravel 102/500 telescope is very universal. No matter if you’re planning to observe moon or planets, explore the beauty of Milky Way or just be amazed by the views of a nature, this wide field telescope is a very good choice. Also if you live in the suburbs of big city, light pollution is very common problem for astronomers. So Sky-Watcher Startravel series refractor could be the best choice for most observations. Always remember, the best scope is the most used one. For lunar, planetary, globular cluster, and binary star observing – as well as for surprisingly good views of the brighter Messier, NGC catalog objects – many amateur astronomers prefer the crisp, high-contrast, diffraction-free images of a refractor. Startravel series optical design includes 2 multicoated for maximum light transition and contrast, air spaces lenses. It’s perfect for lunar observations as well for planetary exploration. You’ll easily see Cassini division and Jupiter belts, with brightest satellites. Discover the beautiful views of brighter deep sky objects combined with wide field of view, or observe the beauty of nature it is a very universal scope. With this aperture you can easily observe most Messier and some NGC objects.
Don’t be concerned by smaller aperture comparing to reflectors. Under average seeing conditions, a useful rule of thumb in astronomy is that this 102mm refractor will usually outperform an average 130mm reflector or Schmidt-Cassegrain for seeing details on the Moon and planets, splitting binary stars, and resolving globular clusters. Why? Unlike reflectors and catadioptrics (Schmidt-Cassegrains, etc.), refractors do not have a secondary mirror obstruction or multiple-reflection optical path to introduce light-scattering diffraction and internal reflections that brighten the sky background, reduce contrast, and smear images. Refractors also have the highest light transmission – the percentage of the light gathered by the scope that actually reaches your eye. It’s a perfect choice if you’re looking for low maintenance, easy to use telescope.
This mount is a perfect companion to small refractors. All-metal alt-azimuth mount is exceptionally sturdy and easy to operate. It features slow-motion control cables on both axes, allowing horizontal and vertical operation. It is perfect for terrestrial observations.
