Specifications:

Magnification:

Telescope magnification is calculated by dividing the telescope's focal length by the eyepiece focal length. A Barlow lens also affects magnification: the power increases according to the Barlow's multiplication factor.

Field of View:

The field of view is the angular size of the sky area visible through the telescope with a given eyepiece. It depends on both the magnification and the eyepiece's apparent field of view. For comparison, the Moon's average apparent diameter is 0° 31' 5" (0.518°).

Exit Pupil:

The exit pupil is the diameter of the light beam that exits the eyepiece and enters your eye. A larger exit pupil produces a brighter image. Exit pupil is calculated by dividing the aperture diameter by the magnification.

Focal Ratio:

The focal ratio (also called f-number or f-stop) is the ratio of the telescope's focal length to its aperture diameter. Telescopes with focal ratios from f/4 to f/6 are typically called "fast" telescopes, suitable for both visual observation and astrophotography. Telescopes with focal ratios between f/6 and f/15 are better suited for visual observation than photography, and generally make it easier to achieve higher magnifications.

Resolution (Dawes Limit):

Resolution is the angular size of the smallest details and objects that can be distinguished through this telescope under excellent observing conditions. This theoretical limit assumes perfect optics and atmospheric conditions.

Limiting Magnitude:

This is the faintest star magnitude visible through this telescope under excellent observing conditions with dark, clear skies and a fully dark-adapted eye.
