H.T. MacGilLIVRAY Royal Observatory Blackford Hill Edinburgh EH9 3HJ Scotland U.K. lAU Symposium No. 161 on 'Astronomy from Wide-Field Imaging', held in Potsdam, Germany, in the course of 23-27th August 1993, was once the 1st convention organised through the recently-formed operating crew of lAU fee nine on 'Wide-Field Imaging'. This operating workforce used to be instigated throughout the XXIst assembly of the overall meeting of the overseas Astronomical Union in Buenos Aires in 1991, and represented a merging of the previous formal lAU operating staff on 'Astronomical images' and the casual 'Digitised Optical Sky Surveys' operating staff. Dr. Richard West used to be 'invited' to be Chairperson, and as a result used to be given the daunting activity of setting up the crowd from scratch. the actual fact that the 1st convention after purely years used to be an important lAU Symposium says a lot concerning the decision and exuberance of Richard West to satisfying the goals of the recent operating crew. The siting of the convention in Potsdam in previously East Germany supplied an outstanding chance to virtue from the political adjustments in jap Europe. sturdy entry to the assembly used to be attainable by means of scientists from jap eu nations, permitting alternate of knowledge at the vitally important Wide-Field amenities in either East and West, info at the wealthy documents of photographic plates that exist in either East and West, and permitting discussions among scientists dealing with very comparable difficulties in either East and West.

Optical wide-field sky surveys have long been basic tools of astronomical investigations.

Spectral lines may be out of the optical range due to large redshiftstt; 3) it may be difficult or even impossible to observe certain types of objects like pulsars, y-bursters, radio galaxies, masers. g. H 1504+65 with T. = 160,000 K). These can only be observed in the IR or X-ray regime; 4) the most abundant elements in the Universe - HI and HeI - are not observable in this range. 2 OPTICAL SURVEYS Present day observers have many tools available to start a new survey project. For example, when searching for primeval galaxies, the possibilities are numerous: multi band observations of large areas using UKST or ESO Schmidt, employing the VLA in the shifted 21 cm HI line, observing narrow lines with dedicated Fabri-Perot interferometer, reprocessing IRAS or ROSAT data, or one can even try to invent something new.
