I want to travel to the stars in our galaxy that are furthest from the centre.
So far I'm about 21 kpc out along the galactic plane and what I thought would be empty space is still teeming with stars (example RS 8409-800-2-32-0)
If I zoom out too quickly (say faster than 400 pc/s) stars seem to stop generating, but I can "bunny hop" by repeatedly focusing on a star and travelling outwards at a slower pace. This seems to generate stars that otherwise would be missed.
How far out will be the last star before we reach the terrible void of intergalactic space?

Hi marasmusine. You can try turning up exposure and limiting magnitude for stars to help make the galactic boundaries, as SE renders them, more apparent. For the Milky Way, the galactic disk experiences a very sharp cutoff in star density at ~21kpc from the center, though some stars still generate beyond this boundary, to ~26kpc.

It'll be really tough to find the actual farthest out star, as it's likely to be a red or brown dwarf considering how many of them exist. At the edges of galaxies, star density is far lower than in spiral arms and that makes the map mode poorly suited for finding weak stars in these areas as you have to zoom out farther to find the more distant stars, and at that point the limiting magnitude is turned down to avoid cluttering the map with those weak stars in denser areas.

I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

That does help, thankyou.
So far I am out to RS 8409-2853-8-658540-0 - a yellow dwarf 28.130 kpc out. It's nice standing on a moon and watching the whole disc of the Milky Way rise over the horizon.

RS 8409-2853-3-260-0 is a lonely red giant 29.481 kpc out.

A related question: Is 100 kpc the largest galaxy diameter that SE generates?
