Mess new spectrograf California group - FINDS Exo-Earths or APF (RPF) ?

On the one hand -

http://www.planetary.org/programs/projects/finds/
The Planetary Society is teaming up with planet hunters Geoff Marcy of the University of California at Berkeley and Debra Fischer of San Francisco State University to help with the quest to find other "Earths," other worlds like our own, elsewhere in our galaxy.
The project is called FINDS Exo-Earths (which stands for Fiber-optic Improved Next generation Doppler Search for Exo-Earths).
This new high-end optical system will be installed on the 3-meter telescope at the Lick Observatory, dramatically increasing discoveries of smaller exoplanets and playing a crucial role in verifying Earth-sized planet candidates from the Kepler planet-hunter mission.


On the other hand -

Automated Planet Finder Telescope: This is a completely robotic 2.4 m telescope under construction at the Lick Observatory (commissioning expected in June 2009), equipped with a high-resolution spectrograph designed to give an RV precision of 1 m s–1 to allow the Doppler detection of planets with masses as small as 5 M⊕.

Automatic Planet Finder (APF): The APF telescope had first light at the EOST factory in Tucson late last Fall and passed Factory Acceptance Tests in February. The telescope is now packed for shipping and due to arrive at Mt Hamilton on April 6 (!). We are on a very tight schedule for signoff by USNO and the Navy before June 30, 2009. There has been a large amount of heroic work going on in the background to work with EOST to bring this facility on line. A crew from EOS has been at Mt Hamilton completing the final punchlist items for the dome and that will be ready for installation of the telescope. The Levy Spectrometer has been largely completed in Santa Cruz for the last 6 months. A new telescope at Mt Hamilton is an exciting event. This particular facility--a system optimized for extra-solar planet discovery and dedicated to that purpose--is extraordinarily exciting.

Pretty neat. I heard that a copy of HARPS was built to help confirm Kepler candidates as well.

I'm sure Kepler will have the same agonizing problem CoRoT has, long follow-up times.

April 21, 2009 the Automated Planet Finder Telescope was installed in the dome! Initial testing showed this to be a very good telescope. By June 11, sufficient tuning and testing had been completed that Ken Johnston of the US Naval Observatory signed off for USNO after reviewing the performance test data and watching the telescope and dome be run through a series of motions.
The UCO contracts with EOS (dome) and EOST (telescope) have additional performance requirements. As of the end of September, we are very close to completion and final signoff. One problem, that the back focal distance is not right for the spectrometer, is being addressed with a new secondary being fabricated and coated in the UCO labs.Once the final acceptance of the telescope and dome is made, the Levy Spectrometer will be installed. All spectrometer components are completed and final alignment and end-to-end testing is starting mid-October.

Gloria and Kenneth Levy provided major support for the APF's spectrometer
