Explanation:
The Massachusetts-based firm of Alvan Clark and Sons became famous for
making telescope optics near the end of the last century.
Near the end of this century, major astronomical observatories still boast of
telescopes with lenses and mirrors made by them including
Lowell Observatory's 24 inch diameter refractor,
the United States Naval Observatory's 26 inch refractor,
the McCormick Observatory's 26 inch,
Lick Observatory's 36 inch, and
Yerkes Observatory's 40 inch refractor - the largest
refracting telescope in the world.
Small observatories too can claim such a link to
telescopic history and many
offer the general public a chance to "look through a classic".
This gorgeous, completely
refurbished 8 inch refractor was
originally bought from Alvan Clark and Sons in 1927.
On Thursdays it stargazes from the
Crosby Ramsey Memorial Observatory dome atop the Maryland
Science Center near Baltimore's Inner Harbor.
