CCD manual for the CCD used

WIYN 0.9m Observatory - This
is the observatory Haverford now belongs to. You can find observing
information on this page, including links to the instruments
available. These instrument links detail the properties of the
instruments and their filter sets.
Almanac online: Stars & Stellar Systems Can use this to identify
Landolt or Johnson standard stars that you will use in your
observations. Be careful to notice which epoch the stars' coordinates
are presented in.
Naval Observatory Astronomical Applications - Tables available for
sunrise/set, moonrise/set, and astronomical twilight. The
astronomical twilight table is helpful to figure out when the Sun is
far enough belwo the horizon to obtain astronomical observations.
(When the Sun first rises, it is already way too bright to observe and
right after the Sun sets it is way too bright to observe).
Seasonal Observability - Enter an observing location, a range of
observing dates, and the coordinates of your observing target, and
you will be given its observability over that observing season. For
Strawbridge Observatory, I have been using "Black Moshannnon
Observatory" from the menu. It is located close to 41 degrees N
latitude and 78 degrees West longitude, with an altitude of 738m
above sea level.
Airmass Table - Enter an observing location, a date, and the
coordinates of your observing target and you will be given its airmass
as a function of time for that night.
Magnitude Systems - This page defines several magnitude systems
(Johnson, Gunn griz, and AB). Perhaps more valuable is that it
provides the number of photons per second that hit the top of the
atmosphere in the UBVRIJHKgriz filters for an m = 0 source.
The Clear Sky
Clock - Look here to get the predicted observing conditions for
the next day and a half.
