Messier 56, The Ancient Stranger

[Datalord]

On my tour around the galaxies globular clusters, I reached Messier 56. I didn't know how unique this cluster was.

Apparently, this cluster came from a merger from another galaxy and its metallicity is just 1% of the sun's. That places it at 13.7 billion years of age, close to the big bang.

Nice report - thanks

Really fascinating objects, globular clusters.

Here is another one, when you are next observing in the vicinity of Lynx:

Wow, that's an interesting story. Yep, I'll have to put that on the list of todo's.

A lovely image as I have come to expect from you, 7 hours on a globular is living up to your name, I do 90mins and think I gave done well, maybe why your images make mine look very second rate.

Thank you very much! 🙏

Honestly, you could call me lazy. Even with these globulars being pretty easy to process, it takes long enough that I want to make sure I have enough good data to get a decent final result. As such I can't be bothered to start processing on a smaller stack and would rather wait another night.
