Where science and tech meet creativity.

The nearest star to the Earth is easily observed during the day. It just happens to be called the Sun. The problem is, it’s quite close and this can make it very hard to observe safely without hurting yourself or hurting your eyes. The current speaker, Lee MacDonald, is discussing several simple rules for attaining good results for anyone who wants to observe the Sun.

Basic Rules:

  • Don’t buy cheap filters or off brand filters. All because the Sun may not hurt to look at, you can’t know that it isn’t damaging your human optics until it is too late.
  • If you are using a Cassegrain telescope of some type (A reflector with a front end corrector lens and rear eyepiece), you must must must use an aperture filter to prevent melting of necessary plastic bits within your optical tube assembly.
  • Remember: When in doubt, project the image and look at the Sun on a screen instead of through the eyepiece

It sounds simply, but quite a few folks have lost an eye or two to the sun.
