There have been many people see telescopes for sale at department stores and the like, and are lead to believe that through a cheap scope, even with "750X magnification", you will see spectacular images the likes of which appear on the box! I don't think I've ever seen a disclaimer that states you will not see those images, or the splendiferous colours, as printed on the box, due to the fact they were originally imaged by the Hubble Space Telescope!
Unfortunately its the astronomy equivilent of anti aging creams, milkshake diets, and ab-blasters...
