Finding a specific star system.

I was wondering if any people out there can help with a thing I'd like to do.

A few years ago, a relative named a star for me. I know star naming is a nonsense scam, but I didn't have the heart to tell her. Anyway, I have a star and a certificate to prove it! :)

I thought it might be fun to find it in Elite, go there and actually claim it, if it hasn't been already.

I have the RA and DEC coordinates, and a catalogue reference with a GSC prefix.

But it's not in the game. Frontier must be using a different way of naming the more distant stars.

Anybody out there know what to do?

Can you google the GSC prefix catelogue and see if you get any results that might include the other Catalogue that can be used in the Galaxy Map.

*edit*

Now I am on a PC and not a Phone

GSC seems to be the Guide Star Catalogue

So step one is find your star in this, once we have it here we might be able to nut out if it appears in the other catalogues or worst case scenario make a best guess if we have direction and distance :)

Success!

After a couple of hours work on MAST and VizieR, and a bit of trigonometry, I identified 'my' star system to be SYNUEFE QC-L B27-1.

So, I bought an Asp and off I went.

27 jumps and 540 ly later... and it's a really dull system. Just a binary, and it's also been claimed. :( Probably got scanned on the way to somewhere else.

Got the exploring bug though, I'm going to take my time getting back. :D

Would it be possible for you to walk through the steps it took to translate your GSC catalog to the Elite Galaxy map in more detail?

I'm very curious how this was done.

I don't have any trig knowledge so you can explain the math as if I were 10 years old, which is probably where my real life math skills are anyway. ;)

Anything you can provide would be helpful. Thanks.

Walk you through it? Well I'll have a go! I was kind of making it up as I went along.

Vasious had the right idea with finding the direction and distance.

What I needed was the right ascension (RA) and declination (DEC), which you may be able to find out from the GSC catalogue number, using this site:

http://gsss.stsci.edu/webservices/GSC2/GSC2WebForm.aspx

I then plugged the RA and DEC into VizieR, this gave the distance (r) and the Galactic Longitude and Latitude (Glon and Glat)

http://vizier.u-strasbg.fr/viz-bin/VizieR

I then had to convert the distance and the direction into something I can use in the Elite galaxy map.

http://en.wikipedia.org/wiki/Galactic_coordinate_system
http://www.metric-conversions.org/length/parsecs-to-lightyears.htm (Where a parsec is 1/r).

This gave a distance of 534 ly in a direction away from the Galactic centre, below and right a bit.

Now, the trigonometry. This is going to be tricky without diagrams. :)

The first triangle finds how far below the Galactic disc we need to travel. Which is about 222 ly.

The second triangle is viewed from above the disc and finds the distance we need to travel away from the centre and to the side. About 475 ly towards the rim and 101 ly to the right.

This gives the coordinates from Sol (roughly) : 101 -222 -475

I plotted this in Elite and found the right area.

To pinpoint the system, I found two nearby stars, HIP 22384 and HIP 22490 that WERE in the database, their RA and DEC were in the right area, BINGO, so I plotted them in MAST.

http://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html?searchQuery=04 46 00.375 +05 41 21.78

This overlaid the star positions onto my target system and I could line them up in Elite. I had to be in the Sol system for this to work.

And there it was!

Good luck to you!

Woah, I'm glad nobody bought me a star, that maths is too much for me :p

As silly as it sounds about naming and all, I think it's kinda cool that for the unforeseen Elite Dangerous future there will be a lot of sky objects discovered and tagged by me there.

Everything's Trig. :)

SOH CAH TOA

So, y'know you do a bit of trig at school and then you get into engineering and the penny drops - it's lots of trig. Mechanics, Vectors, Phase Relationships(electrics), Electronics, Hydraulics... that Pythagoras guy didn't know what he had :)

Don't use any of it now (retired) - but for those studying, well I reckon if you get a grip on Trig, Logs and Differentiation, you have it sorted.... oh, basic math helps too :)

I hate to break it to the OP after all that hard work and research, but Synuefe QC-L b27-1 is not a "real star" - it's a procedurally-generated one, which does not exist in the real universe. It's existence in-game is due to a random number generator, not due to manually-entered star catalogue data. It's location, at a place similar to where you've calculated "your star" to be, is purely a coincidence.

"Your actual star" is not listed in any of the catalogues FD used to generate the "real stars" in the game, so it is not present in the game. Sorry. The procedurally-generated substitute star you have found is as close as you're going to get to it, I'm afraid.

If only FD could link their database with the OSR. Sounds like a good business opportunity:
OSR could add Elite Dangerous to their package and Frontier could sell OSR packages increasing the OSR sales...

Gratz! and have +1 to rep for sticking with it!. DOn't listen to the "Nay Sayers", you have a Star dude! And at some point it was visited by Hippy Darth Vader! How cool is that?!

That it is. ED is a space game, not a spacetime game. Even ignoring the procedurally generated objects, it shouldn't be taken seriously as a model of the Milky Way. It's a nice fantasy though.

By the way, I own 1 square foot of the Moon. :p I think I got it from an ad on a cereal box when I was a kid. Not sure...it was a long time ago. Hmmmm...now where did I put that deed? :rolleyes:

Exactly. When Betelguese finally goes mental, the surrounding systems won't notice for a few years. Anybody IN the system will need a change of pants though.

I don't care if "my star" was procedurally generated or if wasn't. I hope to visit the star for fun. (Sorry my English, I spike 3 idioms, but neither English).

Jalan Bax, how do you calculated ly? I only have coordinates, but not distance.
