Aiming your Telescope at the Sun
Aiming your telescope, with the proper protection, toward the Sun can be problematic. If you use a traditional Finder or a Reflex finder (like a Telrad) you are still look into the Sun.
The easiest way to aim your telescope is to watch the shadow of your telescope tube a move the scope until the shadow is at it smallest possible shape. An extension of this idea if you have a tradition finder scope with mounting rings is to remove the finderscope and replace it with a length of PVC pipe – then watch the shadow of the pipe until it is a circle.
There are “solar finders” on the market which project a shadow or image of the Sun onto a frosted piece of glass. |
