TRES arrived on the mountain on 1 June 2007. After an intense 4 days and nights of tireless work, Gabor Furesz and Andy Szentgyorgyi brought the spectrograph to life on the 1.5m during the night of 5-6 June. The announcement below from Andy and Gabor says it all. Following further work to integrate TRES with the telescope over the next few months, we plan to conduct engineering and shared-risk observations in the Fall 07 trimester. TRES will replace the 1.5m Echelle the following trimester.

Dear Colleague: Last night TRES saw first light. It appears to be working up to expectation.The tip-tilt guide system performs well and the focal reducer produces good guide images. The spectrograph itself produces sharp spectra at the design resolution. The weather was not good, so conditions were far from photometric, but we acquired data on a spectrophotometric standard that will allow us to make a preliminary estimate of the spectrograph efficiency. I have attached some screen shots of the guide system imagery. The first shows the highly confused core of M3, while the second show the sharp round images the guide system produces. Congratulations are due to the long list of contributors to this project, all of whom were essential to the success we enjoy today. Our special thanks to Mark Ordway, the TRES project engineer, whose performance and level of dedication were always above and beyond the call of duty. For major contributions throughout the project, we offer our profound thanks to Steve Amato, Kevin Bennett, Henry Bergner, Mike Burke, Sue Demski-Hamelin, Tim Ellis, Roger Eng, Harland Epps, Dan Fabricant, Bob Fata, Leslie Feldman, John Geary, Larry Knowles, Csaba Major, Tim Norton, John Roll & Joe Zajac. For their support at various phases of the project, we thank John Boczenowski, Pat Brennan, Flo Collette, Emilio Falco, Tom Gauron, Ted Groner, Bob Hutchins, Sylvain Korzennik, Brian McLeod & Wayne Peters. Finally we thank Charles Alcock, Irwin Shapiro and Dave Latham for their encouragement and, perhaps more significantly, their financial support. We look forward an exciting trimester of shared risk observation this fall. Sincerely, Gabor Furesz Andrew Szentgyorgyi
