Observing Log for Mike Durkin


12/26/2011 about 6:30-8:00 PM
Locust Valley, NY
Transparency: 6/10, Seeing 4/5
Temperature: about 30-40 degrees
Equipment: Orion 127mm Mak

Observed variable star RS Cyg before the clouds got too thick.
Even with the clouds, for a while I was able to observe the moon and Jupiter.
I did notice a bit of a line between Mare Serenitatis and Mare Tranquillitatis, dividing the two seas. I don't know if it was a ridge, or maybe a mountain from one of the crater edges casting a long shadow ?
All 4 moons of Jupiter were observed, as well as both equitorial belts, but could not see any sign of the Great Res Spot. Mostly observed with the 17mm eyepiece (90x) and the same eyepiece with a 2x barlow (180x). I also tried using my iPhone cellphone camera on Jupiter through the 30mm and 17mm eyepiece, but wasn't able to get any decent images.

Locust Valley, NY
Transparency: 7/10, Seeing 4/5
Temperature: about 30 degrees
Equipment: Stellarvue 70mm refractor

Observed variable stars Z Cyg and RU Cyg befire it got too cloudy.
During the evening, the tripod tipped over and the scope fell. So far I seem lucky that the only damage was the dew shield was dented.

Temperature: about 20-30 degrees

Tried some DSLR photometry on P Cyg, X Per, γ Cas, and α Ori.
For γ Cas and α Ori, I took a lot of extra light frames to try to build up signal to noise ration so that I could get a decent measurement of some of the dimmer stars.
