     The period for TrES-1 needs only a slight shortening. Transit depth and length also seem to be well-established and are not changing. No anomalies yet.

Good choice of reference stars (no trend or air mass curvature).

Right on time, and a little deeper with CLR than R-band.

Nice having a V-band LC (after 3 yrs).

Cindy Foote's "gold standard" (when she uses the 24-inch) shows excellent agreement with the ephemeris mid-transit time and also transit depth.

The computer clock must have been off 1 hour, so mid-transit occured ~1 minute late, +/- a few minutes. Length is uncertain because ingress was missed. Good depth agreement.
