[QUOTE="ICanFixIt, post: 3479932, member: 45888"] Do some research on some of the astronomy sites and you will learn that this is defying all that is currently understood about optics. The maximum useful magnification of a telescope is about 50x the aperture in inches. Any higher and the image gets too dim and fuzzy to be useful. So a 4-inch scope can get you about 200x before the image gets too fuzzy and dim, a 6-inch scope gets you 300x, and so on. This is not a hard-and-fast rule. Sometimes, when the atmosphere is unsteady, you can only get to 20x or 30x per inch of aperture. [/QUOTE]
