I am in the process of doing exactly what you’re looking for. I have a
piece of software called Cartes du Ciel, which accesses most of the
astronomical catalogues including the ones used for the
Kepner_50lyr_stars.csv file used by AS (Henry Draper & Hipparcos). I am
going through the 50 Light year file in AS, picking on stars at random,
identifying them in the CdC programme and re-naming them with the
appropriate Bayer or Flamsteed number and their constellation location.
I am also trying to relate each one to the T2300 star map. Where there
is no Bayer or Flamsteed equivalent, I am naming them as ?1 Cephei, ?3
Cassiopei, etc and referring to their original Draper or Hipparcos ID in
the Notes section of the AS “Edit Properties” dialogue.

T2300 uses the Gliese Catalogue, which CdC can also access. My biggest
problem is finding enough time to get the job done.

I think that game systems and mechanics should be flexible. I’m not sure
how far Wolf 359 is from Sol but I would suggest something along the
lines of: within 2300AD, you allow a little “reconfiguring of the Warp
Core output matrix” and obtain a “15.27% increase in efficiency”
(thereby placing Wolf 359 within normal jump space :-)

Your list would be very welcome and useful. I have CHView installed if
that is of any help.

Cheers,

Mike

Mike,

2300AD and Traveller 2300 are the same game 1st edition and 2nd edition.
As for converting Botany Bay, Nyotekundu and the like to real star
names, I have access to most of the source material, including the
Colonial Atlas, which gives you the real names to most of the renamed
stars. So I could do that, I have not. Way back in college I typed in
all 777+ stars in the 2300AD near star list included in the game. It
has been said that the 2300AD near star list has a number of rather
significant errors in it. I know that one of them is that Nyotekundu
(AKA Wolf 359) is just a touch closer to Sol than more recent list have
it. Which is significant because Wolf 359 is a the gateway to the most
significant "Arm", the French Arm, in the setting. And without moving
it, it is outside of the 7.7 LY range of the game's FTL drives.

My list of the 50 LY neighborhood does not include the 2300AD names. I
think I started with the list in the CHView program and migrated from
there. I did not keep very good records. But I can always send you my
hand typed 2300AD list as well. I'll just have to break out the old
computer on which it is stored. Which will take a little more time.
Converting it to AS format will not take much time - except for the
multiple star systems and White Dwarves.

I'd love to know how to create a Near Star Map like 2300 AD in AS. Any
ideas?

Dan.

Hi Dan:

This sounds highly interesting. Not to mention the possibility of saving
me a great deal of time. As you will have seen, several others have
expressed an interest. How do you feel about passing your work on to
these guys? Also, is the AD2300 list the same as the T2300 list and were
you able to identify the stars to which such names as “Bessières” and
“Botany Bay” referred?

Finally, can I ask how you tackled the project? The Near Star List from
T2300 contains two reference lists, one from the Gliese catalogue and
the other from what I am assuming is the Bayer catalogue. I have the
Gliese catalogue available on my software but it is rejecting some of
the other identities, so I have doubts about them all being Bayer
catalogue ID’s. I have tried to get AS to show the stars as they are
shown on the T2300 map – were you able to achieve that?

Since the previous paragraph may be a touch off-topic, feel free to
contact me off-list.

Cheers,

Mike

Mike,

I may have done this work for you already. Tonight I will send you my
data sets and see if they are useful to you. You will want to delete
all of the UM, UL and UWD systems from my data set. I made those up.
My game world is strongly influenced by 2300AD (AKA Traveller 2300).

Dan.

I was looking back over some of my old SciFi RPG rules sets and came
across Traveller 2300. It was a great background but I always felt the
systems were a touch laboured. Anyway, my current gaming project (using
my own rules) has reached a point where I need a star map of Earth's
"local" region (50 light years around Sol).

Astrosynthesis provides such a map (kepner_50lyr_stars) where all the
stars are identified by their references in the Henry Draper (HD
numbers) and Hipparcos (HIP numbers) star catalogues. Traveller 2300
contained an excellent star map of the same area of space but the stars
are marked with identities from the Gliese catalogue.

Using an astronomical programme called Cartes de Ciel, which contains
all the relevant catalogues, I am adjusting the Astrosynthesis map to
correspond to the Traveller 2300 one, using more conventional naming
(Alpha Centauri, Rigel, Tau Ceti, etc.). I've no idea how long it will
take (there are well over 500 stars to do in the AS map) but I thought
I'd ask if anyone would be interested in the result. If so, contact me
off-list and I'll make a note to send it to you as an Astrosynthesis
file (you'll obviously need to own AS).

Cheers,

Mike
