The Telrad a star-hopers best friend.
When looking through the Telrad you see the sky thru a window, just as it is, without any magnification. There are no upside-down or mirrored views. You see three red circles that seem to lie floating in front of the stars or objects that you are looking at.
The outer circle is 4 degrees, inner circle is 2 degrees and the center is ½ degree.
If the object you want to observe is visible with the naked eye, just point the Telrad directly at the object. If the object is not visible, using a star charts that offer Telrad guide lines, just align the Telrad according to the chart (typically putting one of the red circles a bright star near the object you want to view) then look thru the eyepiece and the object should be in the field of view.
How to locate M57
First point the Telrad on Vega (Alpha Lyrae).On Map 9 to the right. Then move the telescope in Southeastern direction to the two bright stars Beta and Gamma Lyrae. Put the two degree circle on these two stars, and M57 should be more or less centred in
the field of view.
