TrES-1 second test successful
Taking advantage of the March 13 exoplanet transit on mag. 11.2 host star TrES-1 (19h04m10s +36d38'), using both 4" FSQ106 and 18".
The almost full Moon is about 110 degree away. Wind gusting to 30 MPH but the domes are holding.
Details are shown on the graphs. I am really amazed that even a 4" refractor could capture the 2% dip in brightness, although the data is a bit noisy :-)
The egress images were taken at dawn, I am glad that it was captured too.
