... Meade Instruments Corporation . ... How to Calculate Power . How to Calculate Power: The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed. ... Example: The Meade DS-2070AT telescope has an objective lens focal length of 700mm; when this telescope is used with a 25mm eyepiece, a power of 700/25 = 28 power (written as "28x") results. ... about meade | ...

... Solar System . ... Stars . ... August . ... A classical nova binary system just before an explosion on the surface of the white dwarf. Classical novas occur in a system where a white dwarf closely orbits a normal, companion star. ... A white dwarf is the inert but still white hot core of a dead star. ... This means if you have a dark enough sky the nova is visible to the naked eye but to pick it out you will need to be very familiar with the dim stars between Delphinus and Sagitta (the Arrow). ...
