Hi Sam:

I'm doing something similar although my project is simply re-naming
stars by their constellation designations with letters of the Greek
alphabet and/or Flamsteed numbers or Bayer letters. It was instigated by
my looking at an old RPG called Traveller 2300 and I decided to try to
identify all the stars in the T2300 listing. It's proving a lengthy
process because I can't find the time to work on it at present but I'll

Are you determining "navigation stars" by their absolute magnitude,
detailed spectral classification or what? Obviously, very bright stars
as seen from Earth may well not be very bright when seen from a location
several hundred light years from Earth, unless they have bright absolute

Not all the stars in the "within 1000 light years" listing are
identified by their Henry Draper catalogue numbers - some use other
catalogue ID's. Also, you may well find a few duplications (I did) and
beware of Wikipedia data; because it can be altered by contributors,
mistakes often occur. You're better off using something like or

There is an excellent astronomical programme called Cartes du Ciel which
you can download from,
together with a whole raft of astronomical catalogues - I found it
invaluable when I did my Star Trek universe map.

Subject: [nbos] [AS] Names, not just numbers.

Just so you know, I have a pet project in the works for the long term.

I read classic science fiction as a child, and I've long since lost
track of the times a character in a story had to place himself in the
starfield by finding at least 3 stars he could recognize.

As time becomes available, I'm trying to recreate that starfield as best
I can, starting from the 1000ly kepner data. Mostly what I'm doing is
renaming bodies, i.e " HD 172167" to "Vega (a Lyr)", but where I can I'm
filling in the gaps left by having only a location and "multiple star
system", and changing things like WX UMa from a 'multiple star system'
to a 'close multiple', since the two stars are actually TOUCHING. Also
as I pick out 'navigation stars', the ones that can be seen clearly for
thousands of light years, I'm extending their display distances.

What I'm *trying* for is a map where, with no more knowledge than you
can pick up by browsing Wikipedia, a player "lost" in that map could
actually figure out where he was and choose the right direction to go by
nothing more than picking out stars he recognizes.

With over 2000 *named* stars in constellations within 1000ly, I expect
to be at this for a long time. But at the end, I may have a starfield
that you could recreate a Heinlein or Asimov story in without being
haunted by their shades.

Sheesh, I need to get nbos to hire me to do this. *snicker*
