Lauren U. and Erin A. went out to the telescope to observe the exoplanet transit of TrES-3b.  The evening started off well with Dr. Craig having the telescope already connected so we didn’t have to deal with any errors!  The transit started at 9:40 and ended at 10:56. The images look beautiful with a focus of 2853 and a temperature of 59 degrees.  However, when returning the telescope to home the computer froze once again and had to be restarted.

Lauren U., Erin A., Brandon C., Brian T., and Eli H. went out to the telescope in hopes of observing an exo-planet transit, however, time ran short. So the M-29 cluster was observed instead. Skies were clear and the CCD camera actually worked. However, the computer froze when trying to get flats, darks, and biases, and had to be rebooted.

Elias Holte, Erin Aadland, Lauren Ugelstad, Brandon Crowe, Brian Ternes, and Dr Craig spent around four hours behind the controls tonight with a temperature of 59.7F, focus set at 2842, and with a FWHM of 5.27. Starting around 7:45 everyone but Dr Craig (who arrived around 8:30) worked on getting the observatory up and running. After nearly an hour of troubleshooting Dr Craig came to the rescue and flipped the driver toggle switch to the “on” position. This was much appreciated.

We were able to take data on two objects tonight:

  • M29
  • M15

NOTE: Always make sure anyone in the observatory knows when you’re moving the telescope. Or wear hard hats.

Erin A., Brandon C., Brian T., Eli H., and Lauren U. had a very interesting night.  The night was clear and we were ready to observe the sky, but unfortunately we ran into a problem connecting to the camera.  When we tried to connect, we received a pop up window that said “error opening camera, could not initialize the ccd camera(5).”  We managed to get both Juan Cabanela and Matt Craig on the phone at the same time.  After putting all seven of our heads together, we tried a variety of things and after being unsuccessful we gave up for the night.

Matt Craig, Erin Aadland, Brian Ternes and Brandon Crowe went observing tonight. Very clear night, shot several calibration shots, then science images of:

  • BU Cam (R filter)
  • Kelt-1 b (R filter)
  • NGC 1039 (BVRI)

Air temperature was 36F, focus set to 2830 and FWM around 5. We ended up just taking one image of each science object because people needed to get back to homework.

We also took out one of the 6-inch celestrons and looked at the Moon, Mizar/Alcor, Albireo, the Ring Nebula and Uranus. Technically we probably also had some photons from Pluto hit our eyes too but we couldn’t actually see it.

Nathan Walker, Elias Holte and I observed this evening. The science targets were NGC 6946, TReS-2 b and EY UMa. Seeing was very good (FWHM of 5-6 with focus of 2831, air temperature of 28F) but we hit a number of issues:

  • We forgot to turn on TCS after shooting calibration frames (got some nice star trails, though!)
  • The V filter looks very “foggy”, as it has on occasion in the past. Should probably be cleaned again.
  • Windows had to reinstall the camera driver. Again.
  • I left briefly, and when I returned the telescope was “trailing” again. Wre weren’t sure why, but resetting TCS to user default settings seemed to fix it, for a while, until…
  • …star trails, again. After trying several things I went out to the dome and noticed the hand paddle that hangs from the back of the telescope was pressing against the camera because of the orientation of the telescope. It was pushing down the “N” button (which explained the green “N” I was seeing in TCS) so I rotated the paddle 180 degrees and was back in business.
  • But only for a little while, because the camera died suddenly. Made another trip to the dome and found that the power brick had fallen of the pedestal, unplugging the camera. Plugged it back in and the rest of the night was uneventful.

Nathan and Elias left around 11:30PM, I stayed until around 7AM.

I changed the focus to 2821 around 2AM, temperature had dropped to around 20F.
