[Aavso-photometry] TrES-1

All,

I can only confirm. I did photometry on both HD209458b and TrES-1. It indeed
is significantly more difficult to obtain high-quality results on HD209458b.
In addition, for my latitude, TrES-1 was very high in the sky at the start
of the transit, again positively impacting the photometric accuracy.

I wish all of you good luck in the US with the TrES-1 transit observations
in a few weeks, when the observing window moves from Europe to the US.

Best regards,
Tonny

I've put a rough UBVRI calibration of the field for this
planet transit system on
ftp://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/tres1.dat
I don't trust the absolute calibration very well, but in
relative terms, it is pretty good.  There are a number of
equally bright comparison stars within my 11x11arcmin FOV,
so it should be an easy system to follow (much easier than
HD209458!).
   I'll do a real calibration when the weather permits.
Arne
