Recent wide-field photometric surveys which target a specific field for long
durations are ideal for studying both long and short period stellar
variability. Here we report on 75 variable stars detected during observations
of a field in Pegasus using the WASP0 instrument, 73 of which are new
discoveries. The variables detected include 16 delta Scuti stars, 34 eclipsing
binaries, 3 BY Draconis stars, and 4 RR Lyraes. We estimate that the fraction
of stars in the field brighter than V ~ 13.5 exhibiting variable behaviour with
an amplitude greater than 0.6% rms is ~ 0.4%. These results are compared with
other wide-field stellar variability surveys and implications for detecting
transits due to extra-solar planets are discussed.
