The Copernicus satellite, otherwise known as the Orbiting Astronomical
Observatory 3 (OAO-3), obtained high resolution far- (900-1560 Å) and near-
(1650-3150 Å) ultraviolet spectra of 551 objects, primarily bright stars, from
1972 to 1981.

Founded at the world-famous Royal Observatory at Greenwich in 1877 by William
Christie, then Chief Assistant and later to become Astronomer Royal, The
Observatory Magazine has a special place in the affections of astronomers,
both professional and amateur. It not only carries scientific notes and papers,
but reports the meetings of the prestigious Royal Astronomical Society and has an active correspondence section; it is also renowned for its
authoritative book reviews covering virtually every significant work published
in astronomy.

WEBDA
is a site devoted to observations and data on stars in open clusters. The
database collects information on more than 100,000 stars in some 500 open
clusters. Various facilities are offered to perform selections on star clusters
and access the available data for each cluster. The database query through
cluster maps is a main feature of the interface. A place where anybody should be
able to get the desired data and contribute his or her own observations.

Optical
Correctors for Liquid Mirror Telescopes
One of the often cited limitations of liquid mirror telescopes pertains to the
small region of sky which they can observe. Because the aberrations of a
parabola increase rapidly with field angle, classical corrector designs cannot
yield subarcsecond images for angles significantly greater than one degree. To
access larger fields, innovative corrector designs must be explored.
In these pages we discuss the Optical Design and Testing of a family of
two-mirror correctors to compensate the aberrations of a fixed parabolic mirror
observing at a large angle from the zenith.
