The early bird catches ... epsilon Aurigae :-)
I guess now is the start of the "early morning, 0-dark-100" eps Aur observation season :-). So I did what I liked least (getting up early on Sundays) and hunted for eps Aur.
I was a bit insecure when actually to do the measurement, as there is an obvious trade-off.
Either do it real early, and you still have a pitch black sky, but eps Aur is still kind of low above the horizon and you have an increased risk to get all sorts of unwanted effects like extinction, clouds and haze because the path thru the atmoshere is so much longer.
Or wait until eps Aur rises, but then you'll get increased sky glow from the sun preparing to rise :-).
Hmmm.... how do others here deal with this trade off ?
