What To Look For Through The Telescope
-
Recommended eyepiece: 40 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 look like photographs of galaxies they may have seen. A photograph of a galaxy may have an exposure of may hours. This long exposure brings out the 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.
-
This particular galaxy is bright, compact, and nearly circular.
M94 Information
