The
Telrad is the best-selling non-magnifying finder for Dobsonians,
equatorial reflectors, refractors, and Schmidt-Cassegrains alike.
The
Telrad projects a series of concentric red rings (4 degrees, 2 degrees,
and one-half degree in diameter) on a tilted clear viewing plate at the
top of the finder. These circles make it easy to starhop from object to
object. If a galaxy is 10 degrees north of a known star, for example,
two 4 degree Telrad jumps and one 2 degree jump from the known star will
take you to that galaxy in seconds.
The half-degree circle makes it
easy to quickly center a computerized scope on guide stars for start-up
alignment, and to center on planets, comets, and deep space objects if
you’re scanning the sky manually. The red circles can be seen from
virtually any distance behind the Telrad, from two inches to two feet,
so eyeglass-wearers can easily use the finder.
Collimating knobs at
the back of the Telrad allow you to line up the finder with your main
scope optics. An on/off switch and integral rotary brightness control
allow you to match the finder brightness to your eye’s dark adaptation.
The Telrad uses two 1.5V AA batteries.
