Mike. I should have mentioned that you're not restricted to using the Polaris Correction tables in Vol 1. You can do it from a current almanac using a succesion of little a s: a0, a1, a2. As these are from a current almanac, they shouldn't require a P&N Correction, but it's not my speciality. DaveP
