Skywatcher's Dobsonians are an affordable alternative, and very popular with amateur astronomers of all levels. The 1200mm focal length allows better eyepiece selection to achieve high magnifying power, and the teflon bearing surfaces of the mount ensure smooth tracking ability about both axes. This model is a true "light bucket".
