Observation Notes:
I could not resolve stars or even a vague sense of graininess in this globular. It did have a lumpy, mottled appearance. Averted vision showed an extended halo about 2 arc minutes in diameter. The brighter core region was somewhat rectangular with extensions running toward the northwest. A dull orange star marked the southwest side of the view.
Object Information:
NGC 6207 was discovered by Friedrich Wilhelm Herschel in 1787. Based on his visual impression, he described it as a planetary nebula. It wasn’t until the middle of the next century that d’Arrest revealed it to be a “very crowded cluster”. Difficulty in resolving it can be attributed to its large distance from Earth of nearly 100,000 light years. It is also cataloged as: H IV-50, GC 4244, GCL 47

Dus hier zitten jullie verstopt.When do you come along?
I also observed this cluster through my 8″ reflector to test my scope’s visual limit from my city. I saw a fuzzy spot forming triangle with two stars. This is an easy globular.
Thanks for sharing your observation. This was definitely a nice GC.
