A simple finder for amateur telescopes
on September 10, 2003
The Telrad is an easy to use 1x (that is right one power) reflex finder. I use one with my Meade 8" LX200 telescope. The advantage of a reflex finder is that you can aim the telescope at the area you see with your naked eyes. If I had one of these finders when I started out with my first telescope, I would have spent more time looking at objects than looking for them. It can be used as a complement to the "minature telescope" finders, or with a "Go-To" scope as the only finder. How does the Telrad work? it projects three concentric rings of 4, 2 and half a degree on a transparent window that you look through. The key to using it is to point the telescope at a bright object, then align the reticle (rings) to be centered on the object, and then use the rings to point the scope where you want to observe. The biggest advantage is if you aren't on a target, you can see which direction you need to move the scope without having to make the mental calculation... is my image reversed/upside-down, etc.? The one drawback is that you can only use objects (stars) that you can see with the naked eye. That makes it less useful in light polluted areas. The one thing about the Telrad that is a pet peeve, is that it is large. Also, in damp locations, it is suseptable to dew. There are a number of simple solutions to this. Since installing the Telrad on my LX200, I haven't used the 8x50 finder that Meade sells as standard equipment.
