Jeremy says: with practice, this will be down to a minute or
two. I can do a full HO 229 star reduction in under 3 minutes using
tables. With a calculator it can be quicker.

Jeremy says: I would suggest one of the navigational calculators over
a palm or pocket PC. I have some self-programmed software on my 15 year
old TI-85 calculator which uses AAA batteries and lasts for a year or more on a
single set of cells. Also, my 32 year old navigation calculator runs for a
year or two on 4 AA batteries, even with fairly regular use. I believe the
Starpilot is software in a TI-83 calculator, so I can't see why that wouldn't
last for many months as well, and spare set of AAA cells should be easy to
carry.
