Thanks so much guys. You're right, the answer was to set RA=(LST-6hrs). Assume it would be plus 6hrs if Northern Hemisphere, and Dec should be 90 instead of -90.

Here's the very basic script. Please excuse any odd coding practices - I'm not a programmer. Test it first yourself with finger on the mount control "all stop" button at the ready, just in case. It worked for me tonight, but LST was more than 6. I just added the little if/then in case less than 6 to avoid negative RA, but that bit is untested.
