What To Look For Through The Telescope
-
Recommended eyepiece: 40mm or 80 mm.
-
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.
-
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
-
This galaxy was discovered by Pierre Méchain in 1781.
-
Shown in photographs, the ends of the spiral arms are bright blue, indicating new, blue stars are found there.
