Telrad - Telrad Light Pulser Unit

To see objects through a telescope it must be pointed to exactly the right
spot. The Telrad is sight for pointing telescopes to that ″right
spot″.

Through a Telrad you see the sky the way the star charts show it. Not a small
unside-down and magnified portion of it, but the ″real sky″ with
three lighted target rings set against it. The large ring is 4 degrees
across. It outlines the area covered by a finderscope. The small ring is 1/2
degree across and outlines the area seen in the telescope.

Select an object on the chart and note its position among the visible stars. Then set the
position among the visible stars. Then set the Telrad rings on that spot in the sky. A quick
rough setting will put the object in the field of a finderscope. With no finder, or a faint
object that won′t show, use a more careful setting to put the object in the field of the
telescope.

   The Telrad is 8 inches long. weighs 11 ounces and mounts on any telescope without drilling
holes. It unlocks from its base for separate storage.
