  We discuss preliminary results from our first search campaign for transiting
planets performed using Sleuth, an automated 10 cm telescope with a 6 degree
square field of view. We monitored a field in Hercules for 40 clear nights
between UT 2003 May 10 and July 01, and obtained an rms precision (per 15-min
average) over the entire data set of better than 1% on the brightest 2026
stars, and better than 1.5% on the brightest 3865 stars. We identified no
strong candidates in the Hercules field. We conducted a blind test of our
ability to recover transiting systems by injecting signals into our data and
measuring the recovery rate as a function of transit depth and orbital period.
About 85% of transit signals with a depth of 0.02 mag were recovered. However,
only 50% of transit signals with a depth of 0.01 mag were recovered. We expect
that the number of stars for which we can search for transiting planets will
increase substantially for our current field in Andromeda, due to the lower
Galactic latitude of the field.
