Sleuth: The Palomar Planet Finder
The Sleuth telescope ended its survey in 2008.
The Palomar Observatory's smallest telescope was known as Sleuth.
Sleuth was a robotic telescope dedicated toward the search
for planets around other stars. Specifically it searched
for signs of gas-giant planets passing directly in front
of (transiting) a star.
To do this Sleuth nightly monitored roughly 10,000 stars 6 degree square field-of-view in the hunt for these transiting extrasolar gas-giant planets. This planet finder was the third instrument in a network that also contains STARE (located in Tenerife) and PSST (located in northern Arizona). Candidates identified by Sleuth were then observed by our automated follow-up telescope to rule out most forms of false positives resulting from eclipsing binaries.
