Re: [ATM] Converting ALT and AZ to RA and DEC
Jean Meeus of Belgium has a number of books on things like this. He is published by Willmann-Bell, but I don't see my copy on my bookshelf, unfortunately.

Subject: [ATM] Converting ALT and AZ to RA and DEC
I have programmed my telescope computer to convert RA and DEC to ALT and
AZ for controlling the axes of my dob telescope. However, when manually
slewing the telescope I often find interesting objects that I would
like to track. What I need now are the reverse equations for RA and DEC
of the new found object as a function of ALT and AZ derived from the
encoders.
Can anyone point me an appropriate reference?
