The apparent magnitude that a star would have if it were observed from a standard distance of 10 parsecs,
or 32.6 light-years. The absolute magnitude of the Sun is 4.8. at a distance of 10 parsecs, it would just be
visible on Earth on a clear moonless night away from surface light.
The apparent size of a star’s disk produced even by a perfect optical system. Since the star can never be
focused perfectly, 84 per cent of the light will concentrate into a single disk, and 16 per cent into a system
of surrounding rings.
A telescope mounting using two independent rotation axes allowing movement of the instrument in
Altitude and Azimuth.
In astronomy, the altitude of a celestial object is its Angular Distance above or below the celestial horizon.

light-gathering power.
A measure of the relative brightness of a star or other celestial object as perceived by an observer on Earth.
A unit of angular size equal to 1/60 of a degree.
A unit of angular size equal to 1/3,600 of a degree (or 1/60 of an arc minute).
A small unocial grouping of stars in the night sky.
A small, rocky body that orbits a star.

astrology has nothing in common with astronomy.
The distance between the Earth and the Sun. It is equal to 149,597,900 km., usually rounded o to
150,000,000 km.
The emission of light when charged particles from the solar wind slams into and excites atoms and mol-
ecules in a planet’s upper atmosphere.
The angular distance of an object eastwards along the horizon, measured from due north, between the as-
tronomical meridian (the vertical line passing through the center of the sky and the north and south points
on the horizon) and the vertical line containing the celestial body whose position is to be measured.
Binary (Double) stars are pairs of stars that, because of their mutual gravitational attraction, orbit around
a common center of mass. If a group of three or more stars revolve around one another, it is called a multiple
system. It is believed that approximately 50 percent of all stars belong to binary or multiple systems.
Systems with individual components that can be seen separately by a telescope are called visual binaries

of a multiple star system, it consists of three stars, two very similar to our Sun and one dim, small, red star
orbiting around one another.
The projection of the Earth’s equator onto the celestial sphere. It divides the sky into two equal hemi-
spheres.
The imaginary projection of Earth’s rotational axis north or south pole onto the celestial sphere.
An imaginary sphere surrounding the Earth, concentric with the Earth’s center.
The act of putting a telescope’s optics into perfect alignment.
