M4 Glob In Rho Ophiuchi

[billdan (Bill)]

Here we have the Messier 4 Glob and its smaller companion NGC6144 Glob, part of the Rho Ophiuchi complex.
M4 is 1.3 degrees west of the bright off-axis star Antares and you can see faint horizontal lines from my spider vanes on the right hand side.

Some M4 facts, it is 7,200 light years from earth and is 75 lights years in diameter. With a population of 70,000 stars, it is home to many white dwarf stars which are as old as the universe itself, approx 13 billion years.

Just over an hours exposure, 5x900sec subs, this was one of those passing the time objects while waitng on the Grus quartet to rise higher.

Pleasing colour and interesting contrast between the two globulars. Well done.

Clarification: The Rho Ophiuchii complex is about 360 light years away, whereas M4, although in the same very general direction, is more like twenty times that distance.

Very cool Bill, getting both in your tight frame there

That's very nice, Bill!

[billdan (Bill)]

Thanks all, yes not bad for a quickie.
Thanks for the clarification M&T, I just went by a map I had that had M4 as part of Rho.

That's a nice field of view Bill. A good idea for future targets. Thanks for posting.

[rustigsmed (Russell)]
