First official night of team #2 (2008/12/15)

100% humidity! (And it still is!)
We did not even go to the observatory, and staied at our house, waiting for humidity to go down, in hope that we could go finish setting up the camera, and practice telescope-pointing. But humidity has been at 100% for the last 56 hours!
So not being able to use the telescope, we started drafting our observation plans!

Each target will take about 2 hours of acquisition. WR140 is in Cygnus, and sets early in the night. This means it must be the first target as soon as it is "dark". Next, we have Oe stars to look at. HD14134, in Perseus, will be the next target. Then we should follow the order they come up the sky, for the remainder 3 targets, in order not to flip the equatorial mount. We must also not forget two teluric stars for getting a measure of the continuum to be able to calculate a response function of our equipment. Then there is the callibration frames we need (Neon spectra, Flats, Darks and Bias)
So we are expecting to start working before dinner taking all sort of pointing-independant callibration images, then some spectra of WR140 while having dinner, not forgetting callibration Neon spectra images, then the other targets. Let's hope tonight is a good night.
