This 102/500 refracting telescope from Sky-Watcher is a compact and fast telescope which can find more than 42000 objects in the sky. The F/5 focal ratio results in a short tube (50cm) which is an advantage from transportation point of view. The objective lens is a Fraunhofer-type 2 element lens with multi coating on all surfaces and provides sharp and contrasty images. The 45 degrees Amici-prism can be used for both daytime and astronomical purposes. Recommended for observing the large, but faint objects, but the Moon and planets can also be observed in the magnification range of 15-200x. The rack and pinion focuser accepts 2" eyepieces and accessories. For example, using a 2" star diagonal, a 33mm focal length 2" eyepiece and a 2" deepsky filter at 15x the field of view is 4,5 degrees and even faintest nebulae can be seen in great details (like North America-, Pelican-, Andromeda-, Veil-, Orion- or California-nebula).
The AZ GoTo mount provides GoTO functionalities and tracking as well, so any choosen object can be found ins econds. The hand controller contains more than 42000 objects to choose from or ask the hand controller to recommend one interesting object. The mount requires 12V power which can be provided from the battery pack (included) or from other adaptors or Power Tanks.
The T2 thread makes it possible to attach any kind of DSLR cameras with the proper adaptor, resulting in an 500mm telephoto lens. For solar observations Baader's Solar filter is also available for this scope.
