The BOSS collaboration has now finished their meeting in Cloudcroft, which included several trips to nearby Apache Point Observatory to see the Sloan Digital Sky Survey (SDSS) in action (and even help with observations). We include below a series of photos (taken by Emmanuel Rollinde from IAP) showing the BOSS scientists getting to grips with BOSS and the SDSS telescope

First, need to get a plate (on top) to observe, which are installed in cartridges (one seen at the bottom)

Fill up the (green) BOSS spectrographs with liquid nitrogen to keep the detectors cool during the night
Finally, we provide below two video showing the APO observers and BOSS scientists getting ready for a nights fun. Thanks to Emmanuel Rollinde and Stephanie Snedden for them.
