Abstract
The AstroSat satellite is designed for multi-wavelength astronomy for observations covering a spectral range from soft and hard X-rays to the ultraviolet. The Ultraviolet Imaging Telescope (UVIT) is the only non-X-ray telescope on AstroSat and it provides the long lever arm to the multi-wavelength observations. In addition to the simultaneous multi-wavelength studies in coordination with the X-ray telescopes on-board AstroSat, UVIT is used to study a large variety of objects with arcsecond-level spatial resolution. During the first year of observations, UVIT has obtained images in many filter bands in the wavelength range 130-300 nm over a field of ~28', which are being used to study a variety of hot stars, nebulae, stellar clusters and galaxies.
