Here are two very interesting globular clusters M53 (the brightest one) and NGC 5053. These 2 objects are located in the Coma Benerices. M53 is about 58 0000 light years away from us (and also from the center of the galaxy) and NGC 5053 is 57 0000 light years away. A tidal bridge between the two of them suggest that they interacted a long time ago.
I learned a lot of interesting info reading about these objects, notably that globular clusters are located in the halo of the milky way and are par the oldest objects in our galaxy. These two targets are also considered to be metal-poor clusters, which suggest that they are mostly composed of first-generation stars. These stars are not born out of the matter ejected by previous stars when they die. In astronomical terms, anything other than Hydrogen and Helium are considered to be metals.
If you want an read more about stellar evolution, here is an interesting article:
https://astronomy.swin.edu.au/cosmos/S/Stellar+EvolutionBecause I have a limited field of view, I have to do multiple targets a night. The data was acquired over 8 nights. I had to reject a lot of subs due to high cloud and bad seeing and high clouds.
