Observing Log for Mike Durkin


3/22/2025 about 1:00AM-2:00AM
Locust Valley, NY
Transparency: 6-9/10, Seeing 4/5
Temperature: 35-40 degrees
Equipment: Hutech modified Canon T3i

DSLR Photometry of T CrB. The sky started out this evening looking very clear. However near the end of my session, some thin clouds from the west started moving in, but I think I got my light frames in before the clouds could interfere. Also I did 20 second light frames, which I think is shorter than other sessions of T CrB because 30 seconds would start to saturate the brightest comparison star I use. Hopefully this won't be an issue with the faintest.


3/9/2025 about 8:30PM-10:30PM
Locust Valley, NY
Transparency: 9/10, Seeing 3/5
Temperature: 40-50 degrees
Equipment: Hutech modified Canon T3i

DSLR photometry of γ Cas, κ Cas, ρ Cas, ε Aur, V960 Tau, and V694 Mon. Also visual measurement of α Ori. This is the first time I am trying to take measurements of V694 Mon and V960 Tau.


3/8/2025 about 6:30-7:00PM
Huntington Station, NY
Transparency: 9/10, Seeing ??/5
Temperature: 30-40 degrees
Equipment: none

At Walt Whitman Mall. Mercury was supposed to be realtively close to Venus, maybe within 5 degrees. After eating dinner went out to the parking lot to look. Pretty sure I did see Mercury although it did seem to twinkle more than I expected, perhaps because it was so low to the horizon.


3/2/2025 about 2:00-3:00AM
Locust Valley, NY
Transparency: 9/10, Seeing 3/5
Temperature: 20-25 degrees
Equipment: Hutech modified Canon T3i

Stared up a bit late for DSLR photometry of T CrB. It was a little more windy than I would like. There was also some scattered clouds that was in some of the frames, so I took 20 total light frames instead of the usual 15.
