WARNING: NEVER LOOK DIRECTLY AT THE SUN THROUGH A TELESCOPE, BINOCULARS OR WITH YOUR UNAIDED EYE. 

This is a tool for a known problem: If your telescope has a sun filter (and it must have a sun filter for looking at the sun!), you can't find the sun through the telescope, except it points direct to it. With the sunfinder, it is very easy to find the object. To adjust the sunfinder, make a marker with a pen on the monitor field.

For best results, the monitor field should be printed in white material, but even the full object can be white.

If you have troubles printing overhangs, print the sunfinder in two parts: The projector and the monitor part separately. They can be clipped together.

There are different  designs for Skywatcher and Meade telescopes. 

Use at your own risk!
