The Quest To Find Raxxla

PeteACarter

P
Can anybody translate equatorial co-ordinates to galactic coordinates? Or better still, is there a tool that will do it?

I would very much like to know what systems, if any, are at the following locations, but my math simply isn't up to it.

Right ascension: 1h 1m 3s / Declination: 18° 8'00.000''
Right ascension: 8h 18m 3s / Declination: 1° 1'00.000''
Right ascension: 18h 1m 24s / Declination: 24° 12'01.000''
Right ascension: 6h 5m 18s / Declination: 14° 23'05.800''

Any systems at these locations are my new Raxxla candidates

Not an astronomer, by far, but I assume RA and Declination only gives you the direction of a star or whatever as seen from Earth. No distance, then no coordinates. But I may be completely wrong... Herr Professor-Doktor , please ?

You are right.

They can be calculated to galactic coordinates though. Traditional Galactic coordinates are rotation angle and elevation angle, compared to a line from Sol to Sag A.
https://en.wikipedia.org/wiki/Galactic_coordinate_system

Both these systems need a distance, to give ED coordinates. They are lines from Sol to as far as you want.

EDSM gives both Galactic (with radius) and Equatorial coordinates from ED coordinates so there are ways to convert, if you know the distance. If not, you end up with a equation that gives x,y,z based on (r).

Here is NASA's coordinate system converter: https://ned.ipac.caltech.edu/coordinate_calculator

True, but IIRC it was coupled with the statement "It's a journey everyone has to take for themselves", which is almost certainly not a reference to the interview.

Are you a government agent? :) I just get

https://en.wikipedia.org/wiki/Galactic_coordinate_system Yes. I found this. This was the link that convinced me my math skills were not capable of doing the conversion. Unless we are talking set theory/multi bag theory, I'm a bit useless with maths :)

A line would do, I guess, would take a good while though! And need to be very accurate.

I do wish I had decided to start playing ED on PC rather than PS4, I imagine transposing some lines onto the galaxy map would be comparatively trivial, compared to trying to find specific systems on the line, so I can manually plot a route down it.... 🤯

You dont have to calculate much. The easy way is to find a known system with the correct equatorial coordinates(RA, DEC). Then you enter them in Excel. One line with 0,0,0 for Sol and one for your chosen system. Then you mark all six cells and drag down as far as you want coordinates.
Not 100% accurate, but it's close enough to keep the line, in the galaxy map.

To be fair, in this interview he just confirmed the previously stated " you already said that there will be no clues" (mmmh.. that's true..) mitigating it by the well known tiny little bit obvious - thing.
He just couldn't resist.. :)
(So, there will be no clues. BUT part of it is a tiny little bit obvious, so people know what they are doing.)
But.. who the hell actually knows what he is doing ? Mmmhh ?

Would that be kind of like having a known vector (with the corresponding right RA and Dec) and then multiplicating it by small steps until meeting a system close to it ?

Jepp.

You could do a coordinate search in Simbad, to get an approximate direction to a RL star. Then check with edsm on proc gen systems in that region, to get a more accurate direction.

If you get to far out before finding a good system, you get very long steps. Then you can divide all 3 coordinates by the same number. The vector remains the same.

I hope this wasn't mentioned earlier although I'm sure at some point it was and I might have over looked it. At some point we were all talking about how the middle of the raxxla image looked like it could be a 'crosshair' from one of the various hardpoints/dss/whatever...

Anyways, I was looking on a planet close up on the system map and wouldn't you know, the cursor had the same evenly space three curved lines. I was matching it up to a big crater on the planets surface when I first noticed.

TL;DR
I think we could find possible clues or something in the system map for any systems we may have suspected could be part of the search. And if it turns out to be helpful then it might have been kind of obvious....?
