The performance of the ultraviolet telescope (UVIT) on-board AstroSat is reported. The performance in orbit is also compared with estimates made from the calibrations done on the ground. The sensitivity is found to be within $$\sim $$ 15% of the estimates, and the spatial resolution in the NUV is found to exceed significantly the design value of $$1.8^{\prime \prime }$$ and it is marginally better in the FUV. Images obtained from UVIT are presented to illustrate the details revealed by the high spatial resolution. The potential of multi-band observations in the ultraviolet with high spatial resolution is illustrated by some results. [ABSTRACT FROM AUTHOR]
