NGC2419,Clinton Sterkenburg

NGC2419 was discovered by William Herschel on December 31, 1788.

This globular cluster is one of the most remote globular Clusters of our Milky Way Galaxy both from our solar system and from the galactic center, at nearly 300,000 light years (1 light year = 6 trillion miles) from each. It Has a luminosity with Mag -9.48, according to Harris' database, it ranks fourth after the local group globular cluster Omega Centauri, which is located in the constellation Scorpious, and M54 in brightness. However lucky for us it is in range of medium-sized telescopes, such as the one located in the Calvin Observatory. NGC 2419 is approaching us at about 20 km/sec.

NGC2419 appears to be many stars grouped around a large Object. I am not sure what the object is that holds the stars in place. I can see the object is many thousands of lightyears away, even though its approaching the earth at 20 kilometers a second. I mostly see white light, although I also see some red light mixed in. NGC2419 is 2.6 arc/min in Angular size, although the brightest spot is about 1/3 to 1/2 its total Angular size. Its Diameter is 226 light years.
