Telrad - Telrad Hinged Deluxe Dew Cap

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.
