\chapter*{The Urban Observing Program Objects}
\addcontentsline{toc}{chapter}{\protect\numberline{}The Urban Observing Program Objects}
The Astronomical League Urban Observing Program consists of bright objects selected by Terry Trees for northern observers under light-polluted skies. There are 87 deep-sky objects, 12 double stars, and 1 variable star. The deep-sky objects range in declination from $-35$ to $+72$ degrees, cover all seasons, and include 41 Messier objects and 14 Caldwell objects.
I give finder charts for the deep-sky objects only; the stars are all no fainter than magnitude 5.2 and have Bayer designations, and so a standard all-sky atlas is adequate. I use U1 to U87 to label the deep-sky objects, following the order in right ascension given by Trees, but this is not a standard designation. For completeness, I include all of the deep-sky objects, even bright ones like the Hyades (U18).
The following table lists the deep-sky objects with their J2000 positions (decimal hours of right ascension and degrees of declination), the charts on which they appear in the \emph{Pocket Sky Atlas}, their types, other names, and references to O’Meara’s \booktitle{Deep-Sky Companions} volumes (\booktitle{The Messier Objects}, \booktitle{The Caldwell Objects}, \booktitle{The Secret Deep}, and \booktitle{Hidden Treasures}).
I note that the Hyades (U18) and Coma Star Cluster (U44) are much bigger than the finder charts. They are really binocular objects and better located using a small-scale all-sky atlas. That said, be aware that the $\alpha$ Per Cluster (U15) and Coma Star Cluster (U44) are not labelled in the {\PSA}.
