Real Star Map into Traveller Map

[SanDragon]

What kind of adaptations? Modifications?

I've started my own Solomani sector based on a 3D star map flattened down to 2D, and I don't like how sparse it is beyond 9 parsecs.

I'm hoping to add stars that would not be seen from Earth due to low luminosity, but I don't know if such a thing was considered when the Interactive Atlas of the Imperium was made.

And the math to figure out what luminosity of a star would still not be seen at each hex from Earth just boggles.

If you've already done this work, thank you!

The main modifications were:

1) "Flattening" it to 2D (real space is 3D).
2) Fitting it to a hex grid (i.e. rounding distances).
3) Adding a few "yet undiscovered in 2011" dim stars, typically brown and red dwarfs and K class stars to round things up (plausible but not based on "real data"). These are the "NSSC" stars you'll see on the OV map.

Sound like reasonable mods.

And I just downloaded it, so more of my precious time is about to be crushed.

Many thanks!

AstroSynthesis is awesome for this, and goes into phenomenal detail, ...and of course if you want to obtain really good star charts of our arm of the Milky Way Galaxy, here is an excellent place to start;

FWIW, I have used ChView in my own writing. It gives sufficient data on the stars as a starting point, as well as distances between each star.

Now, I'm annoyed.

I downloaded this and tried to print selected maps for my own use, but kept having trouble with it. This was a few months ago.

Now, I can't find it on my computer, nor is it in my Drive Thru RPG library.

Grrr...

Downloaded what? Astrosynthesis?

As an aside, one star about ten hexes from Terra just got some interesting Library Data.

Downloaded what? Astrosynthesis?

Umm... No.

Sorry. I seem to have problems being specific lately.

I downloaded Golan's Outer Veil pdf...

I had a computer crash and apparently didn't do a backup of my computer, so the pdf is now gone.

Nor is it in my virtual library at DriveThru.

There is an old Challenge or Travellers Digest I forget which one but has the American Arm from 2300AD in a 2D format.

Just been populating this. Local part of the Solomani Rim adjusted to real positions ("height" in and out of the page not yet shown).
