Department stores and so-called Discount stores often sell telescopes designed to appeal to novice observers with limited observing experience. Advertisements for these telescopes promote purchases with slogans and jargon. These advertisements emphasize low price and high power and ignore more important technical information such as eyepiece size, effective power, mount type, mount stability, optical quality, and focal length.
