ASTRO: NGC 2419 A far out globular

At about 300,000 light years from the core of our galaxy this far out in
many senses of the term. If you moved it to where M13 is, it would be
as big as the full moon! Now that's FAR OUT just to contemplate! At one
time it was thought to have escaped from some galaxy and was just
wandering among the galaxies of the local group but it is now thought to
be orbiting the Milky Way, just that it is at its farthest point ready
to dive back through the disk again. Is it big because it orbits so far
out it has made far fewer trips though the disk of the galaxy and thus
lost fewer stars. Were the nearer globulars this big at one time?
Anyone know the thinking on this?

Somehow I doubt I'll be around to see it when it gets that close. Just
my luck.

Nice Alberio double to the right (WDS STF 1118). It's blue star as well
as the other 7th magnitude star are both spectral class A stars. I took
this through a haze and the blue from them really tore through the
image. I toned it down a lot. Bright blue stars and a haze don't mix
for imaging I discovered! Even the G0 star to the far left cast a blue
glow.

Rick,

I'm still reading a text on globulars, but I believe that your
speculation is correct. Most glob's have lost a lot of stars. Some of them
(including 2419?) probably came from other dwarf galaxies that the Milky Way
has cannibalized (or at least that idea is supported by unusual metal
content in the stars).

I've had this one on my 'target list' for years, but I've never gotten to
it. Your image has great resolution and is a beautiful picture, despite the
'blue haze' effect.

I'm not a big glob fan but that is cool with those big bright guys and that
close double nearby

what a nice composition

Great image Rick!
