RA/Dec to alt/az & catalogs

I'm thinking of starting the OC certificiate from the Astrnomical League. Unfortunately, I don't have all of the catalogs where the required OCs are listed. Also, most always locations are given in RA/DEC. I'm using a dob with a magnetic protractor to get altitude. How can I convert RA coordinates to alt/az, and where can I get the catalogs required? Thanks for the guidance. Mark

Mark,

regarding cnverting the RA/DEC coordinates to ALT/AZ--

Instead of converting, why not just use a planetarium program like the Sky or Cartes Du Ciel to tell you where an object is. I mean, if you are carting around a computer to help you with conversions, you might as well have a planetarium program in it.
