I want some day to travel to this star but can't find it using in-game galactic search. Do I something wrong or what?

Newcomer / Intro Does XTE J1739−285 exist in Elite? How to find it?
- Thread starter Fuming Coffee
- Start date
It had previously been claimed that XTE J1739−285 was the fastest-spinning celestial body yet known, with a frequency of 1122 Hz. However, a re-analysis of these data by other astronomers has been unable to reproduce this result.
XTE J1739−285 has been proposed as a possible quark star.
Even if it was discovered already in 1999, I somehow highly doubt it is in game:
You could convert the location to in game galactic coordinates and look if there's a procedurally generated neutron star close enough so you can claim that to be XTE J1739−285.

How I can convert the location?
Oh, It looks like I should use this website. Okay. Thank you! ❤
Alas, that is beyond my ken.
IIRC there are some tools, or at least info on how to do it, around.
The galactic coordinates are 359.7138 +1.3005 and a distance 39,000ly from earth.
These translate to game coordinates of approximately 195 , 885 , 39000.
Which almost 13,000 ly on the far side of Sag A*.
edit:
sorry, should be -195, 885, 39000. Which is near Spooreau BK-M c9-36 , but I couldn't find a neutron star close.
The distance of 39k is only very approximate, so any neutron star along the z axis from 35k to 45k could be a candidate.

Thank you so much!
How to search real coordinates and translate in game like you did?
You could try:

Converting Legacy Coordinates to XYZ | Canonn Research Group
Occasionally people will research the ancient star maps looking for star systems that may have had different names back in the 21st Century so that the can go visit them. Or they may wish to visit the nearest star in the milky way to another galaxy so they can get an uninterupted view. We will...

The link to "Converting Legacy Coordinates to XYZ" is a bit confusing because it talks about galactic coordinates and then converts ascension and declination, "RA and Dec", to XYZ. Unfortunately RA/Dec are not the same as Galactic coordinates.Thank you so much!

But in this case the maths is simplified because the galactic angles are so small.
The SIMBAD link says the galactic coordinates are 359.7138 +01.3005.
The longitude angle L is almost 360 which means L = 0.2862 degrees "left" of the line to Sag A* , the base line.
The +1.3005 degree line will be "up" from the base line by 1.3005 degrees.
The distance to the object is 39,000ly, according to wikipedia. But this is only an approximation - distances being harder to find than the angles.
Normally you would need to transform the coordinates from spherical coordinates to cartesian XYX, but because the angles are so small we can just calculate "left" and "up" separately using the arc length formula arc = R.angle ( in radians)
So the angles must be converted to radians :
0.2862 degrees = 0.005 radians.
1.3005 degrees = 0.0227 radians.
Finally we can just multiply by the distance (R) 39,000 to get
x = 39,000 * 0.005 = 195
y = 39,000 * 0.0227 = 885
z = 39,000
Because the x coordinate is left of the base line, the coordinate in the game is negative, ie -195,885,39000
Doing the conversion for bigger angles is much more complicated, but is a standard spherical to cartesian coordinate transform.
