Resolving power, measured in arc-seconds, is the ability to discriminate between two close points, such as double stars, or to reveal detail. The celestial sphere is divided into 360??, each degree is divided into 60 "arc-minutes." These arc-minutes are further divided into 60 parts, each called an ...

Yes. Two easy ways to change magnification: 1) Change to a different focal length eyepiece. Shorter focal lengths increase magnification, longer focal lengths decrease magnification. 2) Add a "Barlow" lens between the telescope and the eyepiece. A Barlow lens system can double or triple magnificatio...

Divide the focal length of the telescope optical system by the focal length of the eyepiece. The result is magnification (x). With a refracting telescope, the objective lens focal length alone may be used for this calculation. In some reflecting telescope designs, the net focal length may be greater...

We call objects associated with the planet Earth "terrestrial." This includes birds, whales, people, ships, landscapes and butterflies. We regard space objects beyond Earth's atmosphere as "astronomical." Examples include the Moon, planets, comets, stars, galaxies, nebulae, and the Sun.

All telescopes collect light and focus the magnified image on a single point. We classify telescopes by their intended application and by their optical design. The two main applications are terrestrial (spotting) and astronomical. The two principle optical designs are reflecting and refracting. Refl...

The "best" telescope is the one you will use the most! Ask yourself, "What do I want to see -- earth objects, space objects, or both?" The answer should reveal whether you need a "spotting scope" or an astronomical telescope - or one that will handle both terrestrial and space objects!
