... Almost all DSOs require a telescope to see in any detail at all, though some can be detected with just binoculars, and a few can be barely seen with the unaided eye. ... DEGREE: Distances on the sky (sometimes called the celestial sphere) are measured in angular degrees rather than inches or feet. ... The magnification is the focal length of the telescope divided by the focal length of the eyepiece. ... Short focal length eyepieces are also termed high power, long focal length are low power. ...
