Abstract:
An observational program, called a Key Program, that uses a sample of clusters of galaxies from the revised and south extended Abell catalog (Abell, Corwin and Olowin, 1989) is briefly described. The Leiden ASTROSCAN plate-measuring machine is used to scan photographic plates, i.e. glass copies of the red PSS for the northern clusters and film copies of the SRC survey for the southern clusters, to obtain catalogs of galaxies for each selected cluster.

Abstract:
Recent observations of 20 and 50 km/s clouds are reported focusing on the determination of temperature through a large part of the clouds. Results show a kinetic temperature of about 25-70 K in the 20 km/s clouds, and of about 80-90 K in the 50 km/s clouds.

Abstract:
Observations performed during September 1990 using the 15-m SEST telescope at La Silla to study the 1.2-mm continuum emission of a complete sample of galaxies selected from the IRAS Point Source Catalog are described. The sample includes 61 galaxies with a 60-micron flux above 2 Jy in the sky region limited by the equatorial coordinates. These observations provided reliable detections and upper limits for half of the sample objects in the delta range from -22.5 and -26.5 deg.

Abstract:
The current use of Schmidt telescopes is reviewed to determine advantages of photographic methods over CCDs. It is concluded that the photographic technique is better suited than CCDs for wide-field, high-angular resolution Schmidt telescope work. The large size and archival properties of photographic plates make them indispensable for the permanent recording of large sky areas during optical sky surveys.

Abstract:
Testing of astronomical mirror blanks based on build-up and electron-beam welding is described. It is concluded that both aluminum mirror technologies, build-up and electron-beam welding, proved to be adequate for the manufacturing of 2-m-class astronomical mirrors. Optical tests were very successful and extrapolation to larger diameters is considered to be feasible.
