Observing Log for Mike Durkin
11/28/2010 8:30PM-11:00PM
Locust Valley, NY
Temperature: about 30-40 degrees
Transparency: 9/10, Seeing ?/5
Equipment: Hutech modified Canon Rebel XT
I took some images of the area around ε Aur, in order to plug into
the Citizen Sky Photometry speadsheet. This is to find the color transformation
coefficient and also the extinction coefficient. I took two sets of images,
separated by about 45 minutes to get different airmass values.
11/27/2010 11:30PM-2:00AM
Locust Valley, NY
Temperature: about 40 degrees
Transparency: 9/10, Seeing ?/5
Equipment: Stellarvue 70mm
Observed some variable stars: γ Cas, W Per, Y Per, α Ori. I also
observed RY Cam, but I wasn't using valid comparison stars. I did find
what is probably a good chart after fishing around the AAVSO site a little.
I also observed M45, M42, M43 and M41.
11/12/2010 11:00PM-2:30AM
Locust Valley, NY
Temperature: forget, but probably around 50 degrees

Equipment: Hutech modified Canon Rebel XT
I wanted to try to use my DSLR to take some photometry measurements of
Algol during it's eclipse. The middle of the eclipse was at about 00:52 AM
local time. I was able to get fully set up around that time, so I may
have missed the eclipse just before the minimum. I took images about
every 5-10 minutes until about 2 AM, by that time the camera lens was
starting to get dew.
Here is a graphy of my photometry measurements which can clearly show Algol
beginning to brighten:
