What To Look For Through The Telescope


  1. Recommended eyepiece: 40mm or 80 mm.

  2. When people look through the telescope they should see a fuzzy patch of light. This is the galaxy. If they are having trouble seeing it, have them look at a star near the edge of the field, then look back to the center out of the corner of their eye.

  3. The view through the telescope will not be like the photographs they may have seen. A photograph of a galaxy may have an exposure of many hours. This long exposure brings out spiral arms and other details. Our eyes allow the light to collect for only about 1/30 of a second before they refresh themselves and start over again.


M106 Information


  1. This galaxy was discovered by Pierre Méchain in 1781.

  2. Shown in photographs, the ends of the spiral arms are bright blue, indicating new, blue stars are found there.
