Cagliari Astronomical Observatory ( International Latitude Station )
The Cagliari Astronomical Observatory was established as International Latitude Astronomical Station of Carloforte in 1899, a small town of the sardinian island of S. Pietro. It has been, for about 80 years, one of the five international stations devoted to study the Earth rotation and polar motion. Observations with the zenital telescope were carried out, except in the period of the second world's war. Starting from 1978, the headquarters were moved to Punta Sa Menta, a site 15 km far from Cagliari which has the same latitude of the Carloforte station.

ESO-MIDAS is the acronym for the European Southern Observatory - Munich Image Data Analysis System which is developed and maintained by the European Southern Observatory. The MIDAS system provides general tools for image processing and data reduction with emphasis on astronomical applications including imaging and special reduction packages for ESO instrumentation at La Silla. Volume A describes the basic MIDAS system with all general purpose facilities such as MIDAS Control Language, all available commands, data input/output (including plotting and image display), table system (MIDAS Data Base). Site specific features are given in an appendix. Volume B describes how to use the MIDAS system for astronomical data reduction. Application packages for special types of data or reductions (e.g., long slit and echelle spectra, object search, or crowded field photometry) are discussed assuming intensity calibrated data. A set of appendices gives a detailed description of the reduction of raw data from ESO instruments. Volume C gives the detailed description for all commands available. This volume is not available to remote users as the complete volume as it is accessed via the MIDAS GUI XHelp.

Hipparcos
Hipparcos is a space experiment dedicated to the precise measurement of the positions, parallaxes and proper motions of the stars. The intended goal was to measure the five astrometric parameters of some 120 000 primary programme stars to a precision of some 2 to 4 milli-arcsec, over a planned mission lifetime of 2.5 years, and the astrometric and two-colour photometric properties of some 400 000 additional stars (the Tycho experiment) to a somewhat lower astrometric precision. The project was accepted within the ESA scientific programme in 1980. The satellite was launched by Ariane, in August 1989, and after collecting more than three years of extremely high-quality scientific data, communications were terminated with the satellite in August 1993. All of the mission goals have been achieved, and in most cases significantly exceeded. The first results are expected to be available to Principal Investigators during 1996, and widely distributed early in 1997.

Hubble Space Telescope Astrometry Science Team
See how astrometry, one of the oldest branches of astronomy, uses the Hubble Space Telescope, one of the newest tools of astronomy. Interrogate our home page to find out what we do, who we are, and what we've done. Look over our shoulder as we search for planets around a nearby star. We use the Fine Guidance Sensors aboard the Hubble Space Telescope (HST) to measure star positions, study binary stars and study stellar motions. Primarily, stellar positions yield parallaxes which provide information on distance. The distances to nearby stars calibrate the entire astronomical distance scale. Monitoring star position may reveal previously unseen companions. We search for planets near Proxima Centauri and Barnard's Star. We also work to tie the HIPPARCOS reference frame to an extragalactic (non-rotating) reference frame. We study binary stars unresolvable using ground-based techniques. We inspect stars to determine whether or not they are binary. We use the Planetary Camera to obtain images of stars in globular clusters. The precision with which we can measure positions is so high, that after 3-5 years a second image will show motions of stars in clusters 6 kpc distant.

Optical Correctors for Fixed 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.

POST is an ultralight 4m diameter telescope suspended at an altitude of 12km (40,000ft) from a 90m aerostat above a base near Fairbanks, Alaska. The large mirror (the Hubble Space Telescope mirror is only 2.5m in diameter) when operated in the cold, thin, dry polar stratosphere will provide images whose resolution rivals that of HST, and exceeds that of any ground-based telescope including Keck. The intensity of the images is ten times stronger than HST. In the infrared, POST will detect galaxies in the early universe which are 10 times fainter than those that can be detected with any present or planned space or ground telescope. POST will take images and data in the infrared beyond 2 microns where HST is ineffective and in spectral windows which are closed to ground-based telescopes.

The MACHO project
The MACHO project is searching for dark matter in the form of Massive Compact Halo Objects (MACHOs) using gravitational microlensing. We search for these events by monitoring over 10 million stars every night in the LMC and Galactic bulge, using the dedicated 50-inch telescope at Mt. Stromlo.

The Whole Earth Telescope ( W.E.T. )
In 1986, astronomers from the University of Texas established a world--wide network of cooperating astronomical observatories to obtain uninterrupted time--series measurements of variable stars. The technological goal was to resolve the multi-periodic oscillations observed in these objects into their individual components; the scientific goal was to construct accurate theoretical models of the target objects, constrained by their observed behavior, from which their fundamental astrophysical parameters could be derived. This approach has been extremely successful, and has placed the fledgling science of stellar seismology at the forefront of stellar astrophysics.

Two Color (U,B) Survey of Galactic Plane ( Lanning UV Survey )
In 1969, a two-color survey of the galactic plane was begun using the Palomar 48-in Oschin Schmidt telescope under the direction of Allan Sandage. The intent of the survey was to support the Uhuru X-ray satellite (launched in 1972) in an effort to identify the optical counterparts of newly detected x-ray sources. Each plate was exposed through the Blue (GG13) and UV (UG1) filters with images offset by 12 arcsec. The exposure times were selected such that the U-B color was balanced at U-B=0 for equal sized images. The hotter the star, the bluer (larger) the UV image.

University of Ljubljana, Astronomical Observatory ( Slovenia )
The Ljubljana Astronomical Observatory is part of the Department of Physics and is located on the hill Golovec close to Ljubljana. Observations that require dark skies are obtained at Crni vrh observing station where two small automated telescopes equipped with state of the art systems for CCD photometry are located.

Astronomers run university courses of astronomy for astronomers as well as physicists and primary and secondary school teachers. The Observatory has a public astronomical library. Research is in large part done in collaboration with the Astronomical Observatory of Padua. Reseach interests include general relativity, active galactic nuclei, close stellar binary systems, pulsars, comets and telescope automation.

Whately Telescope
Whipple Observatory
Wisconsin H-Alpha Mapper ( WHAM )
The Wisconsin H-Alpha Mapper will produce a survey of H-Alpha emission from the interstellar medium (ISM) over the entire northern sky. The instrument combines a 24-inch telescope and a high-resolution, 6-inch Fabry-Perot spectrometer to achieve 8-12 km/s velocity resolution in one-degree beams on the sky. By utilizing CCD technology, we hope to attain a sensitivity level of 0.01 Rayleighs. This survey, the first of ionized hydrogen in our galaxy, will be used to explore the spatial and kinematic structure of the warm ionized component of the ISM. WHAM is currently at Pine Bluff Observatory but will move to Kitt Peak, Arizona in the Fall of 1996 for the survey, which should take about 2 years.
