For 2 months I have the Celestron Skymaster and could now test extensively under southern skies. Wonderful: the whole deep sky objects in the southern Milky Way. The objects known as globular clusters M13, Andromdanebel, Great Orion Nebula beautifully. The moons of Jupiter. Watch else with a 20 cm Dobson levels, the course is longer and man / woman must not, of course, have the colored glossy pictures of the sky from several hours exposure in mind. Important for long-term observation is a good holder for screwing on a solid tripod. The first compound of plastic was brand "Wackeldackel". Outdoors in light winds and smallest touches the stars dance before his eyes. The decay takes forever, previously comes the next gust of wind. So: Be sure the sturdy tripod adapter from metal purchase (eg Galaxster on Amazon). Then the observation is a pleasure.
