Finding Charts:
Digitized Sky Survey
To use the DSS to make finding charts, either enter the object name to get the coordinates or enter them yourself (make sure you select the correct epoch - J2000 or B1950). Set the file format to GIF so that you retrieve an image that you can see in your web browser.

You can also use Skyview or the SDSS finding chart tool.

Totally coolest site:
Clear Sky Clock for Philadelphia (specifically, at Northeast Philadelphia Airport). This is a prediction for the next two days based on computer models. Pay your money, take your chances. This site also has several excellent links to satellite data and other astronomy info as well as star maps customized for the Philadelphia area. To understand the difficulty of doing optical astronomy in Philly, see the light pollution map.
