We have performed a deep, wide-field imaging survey of the Pleiades cluster (Melotte 22) in the R and I-bands to search for very low-mass stars and brown dwarfs. The survey extends over ~ 2.5 square degrees around the cluster's center down to a ~ 90% completeness limit of R ~ 23 and I ~ 22. We find 26 objects whose location in the (I, R-I) color

We present the results of a three-year campaign of broad-band photometry in the near-infrared J, H, K and L' bands for a sample of approximately 250 giant stars carried out at the Observatorio del Teide (Tenerife, Spain). Transformations of the Telescopio Carlos Sanchez system into/from several currently used infrared systems are extended to the

A search for bright galaxies associated with radio sources from the Westerbork Northern Sky Survey (WENSS) minisurvey has been carried out. A galaxy counterpart was found for 402 of almost 10,000 radio sources. Of these a radio and optically complete sample, with a flux density limit at 325MHz of 30mJy and a limiting red magnitude of 16, can be

ABEL is currently at the beginning of the design phase at the Instituto de Astrofisica de Canaris. The instrument will be equipped with the 256 X 256 Santa Barbara Research Corporation InSb FPA which will provide a working spectral range from 1 to 5 microns. For image mode three different platescales are envisaged: 0.2 inch/pixel, to be used in the
