Appendix C - RS-232 Connection
Using the included NexRemote software you can control your NexStar telescope with a computer via the RS-232 port
located on the computerized hand control and using the RS-232 cable . For information about using NexRemote to
control your telescope, refer to the help files located on the disk. In addition to NexRemote, the telescope can be
controlled using other popular astronomy software programs.
The minimum detectable angle an optical system can detect. Because of diffraction, there is a limit
to the minimum angle, resolution. The larger the aperture, the better the resolution.
The angular distance of a celestial object measured in hours, minutes, and seconds along the
Celestial Equator eastward from the Vernal Equinox.
This is the angular speed at which the Earth is rotating. Telescope tracking motors drive the
telescope at this rate. The rate is 15 arc seconds per second or 15 degrees per hour.
The boundary line between the light and dark portion of the moon or a planet.
The totality of astronomical things, events, relations and energies capable of being described
objectively.
A star whose brightness varies over time due to either inherent properties of the star or something
eclipsing or obscuring the brightness of the star.
The period of the moon's cycle between full and new, when its illuminated portion is decreasing.
The period of the moon's cycle between new and full, when its illuminated portion is increasing.
The point on the Celestial Sphere directly above the observer.
The zodiac is the portion of the Celestial Sphere that lies within 8 degrees on either side of the
Ecliptic. The apparent paths of the Sun, the Moon, and the planets, with the exception of some
portions of the path of Pluto, lie within this band. Twelve divisions, or signs, each 30 degrees in
width, comprise the zodiac. These signs coincided with the zodiacal constellations about 2,000 years
ago. Because of the Precession of the Earth's axis, the Vernal Equinox has moved westward by
about 30 degrees since that time; the signs have moved with it and thus no longer coincide with the
constellations.
