NGC 3201 (also known as Caldwell 79) is a low galactic latitude globular cluster in the southern constellation of Vela. It has a very low central concentration of stars. This cluster was discovered by James Dunlop on May 28, 1826 and listed in his 1827 catalogue. He described it as “a pretty large pretty bright round nebula, 4′ or 5′ diameter, very gradually condensed towards the centre, easily resolved into stars; the figure is rather irregular, and the stars are considerably scattered on the south.”

 

Regarding NGC 3201, I collected photos of their reddening and de-reddening with the Skynet Robotic Telescope Network.

de-reddened

The reddened image is what it looks like as observed on Earth, and the de-reddening makes the cluster look cleaner.

 

The above chart is based on the motion, distance, age, metallicity and E(B-V) values of the cluster.

Motion in RA: 3.3 mas/yr

Motion in DEC: -1.9 mas/yr

Distance: 5.52 kpc

Log(age): 8.86 log(yr)

Metallicity: -1.46 solar

E(B-V): 0.18 mag

 

Through observations of star clusters and analysis of data, I have discovered many interesting and amazing things about the universe. Exploring and discovering the universe has allowed me to learn more about star clusters and galaxies. I hope more people can join in analyzing and exploring the universe, because when you immerse yourself in the world of astronomy you will discover the fun and mystery.
