The first website dedicated to amateur radial
velocity studies
Spectrashift.com is a collaborative
effort of amateur astronomers from around the
world. Our goal is to construct a 1.1 meter
telescope and spectrograph to discover extrasolar
planets using radial velocities.
We have already demonstrated a level of capability
by detecting the known planet around the star
Tau Bootis. Information on our publication in
the Journal
of the British Astronomical Association can
be found here
