Bill,

I have embarked on the long task of creating a program that does sight
reductions without an paper almanac. I am going to replace the paper almanac
with the JPL Planetary and Luner Ephemerides which is available on CDROM
from Willmann-Bell, among other places. While I am quite aware that this has
been done before, I am doing it as an intellectual excersize. While not a
calculator person, I applaude your efforts.

I didn't want you to think you were a lonely voice in the dark.

Regards,

Vic
