RedAlert,
I am mostly trying to find systems in the near Sagittarius and Perseus arms.
Since I have no astronomical expertise whatsoever, I'm not sure what you mean by celestial or galactic coordinate systems, but since I'm essentially abandoning scale, I wanted to try and fit a whole galaxy in the last scenario, so some such galactic coordinate system will be used for all of them.
And yes, south in my scenario is towards the galactic center. And yes, I agree that direction is the most important thing. I want systems that are farther away from the galactic center to be 'away' from the player.
I'll update some screenies to show you what I came up with, and any suggestions for famous stars and such will be greatly appreciated.
I should apologize, first of all, because it appears I've had a little terminology confusion: I have fallen into the habit of referring to the Equatorial Coordinate system as 'Celestial', which is not very correct or accurate.
I don't think this is really necessary for you to know, because judging by the position of the stars on your map, I'm almost certain it's based on Galactic coordinates, but here's a summary of those two coordinate systems, for your interest.
The
Equatorial Coordinate System, using Earth as the centre point, treats 'up' and 'down' in space as extensions of Earth's north-south axis, and the fundamental plane is an extension of the Earth's equator into space. Stars are coordinated by their location, in degrees, around this plane; and by their location, in degrees, above or below it.
What is very important to understand is that up and down, as extensions of Earth's north-south axis, are completely different directions than the galactic 'up' and 'down', that is, the directions perpendicular to the galactic plane. Therefore, we have the Galactic coordinate system.
The
Galactic Coordinate System still treats Earth as the centre point, however, as mentioned, up and down are directions perpendicular to the galactic plane, while the fundamental plane is parallel to the galactic plane. Like in the equatorial coordinate system, stars are coordinated by their location, in degrees, around the fundamental plane, and by their location, in degrees, above or below it.
Sorry for dragging this off topic. I'll stop now!
