M45, the Pleiades Star Cluster
A striking sight in the
fall and winter skies, the Pleiades have enchanted stargazers
ever since there were any to be enchanted. Its hot blue stars
reflect their light from the dust clouds in which they are
immersed. These faint nebulae are only dimly visible in a
telescope, but are not difficult to photograph.
This was made with my 92mm
refractor. The image does not go deep enough to reveal a
strange truth: the Pleiades reside in a hole in a surrounding
very faint cloud, a situation which can be eerily glimpsed in
a fine telescope on a very dark night.
