ASTRO: Palomar 10 One of the better Palomar globulars
Palomar 10 is Sagitta's "other" globular cluster. It is about 19,000
light-years distant and about 21,000 light-years from the center of our galaxy. To see it you have to look through some of the heavy dust in our galaxy. To come through as strong as it does (magnitude 13.2) it must be a much grander object than what little gets through to us. Because of all the dust it is severely reddened. It was discovered by A. G. Wells in 1955 making it one of the earlier Palomar globulars found. It is one those with a 12" scope or larger should have little trouble finding though even in large Dobs of 30 inches only 3 to 5 stars are seen in it. There is little on this globular. It is surprisingly metal rich. The only paper on it I found is at: http://adsabs.harvard.edu/full/1997PASP..109..920K The paper covers a similarly obscured but brighter globular NGC 6749 as well as Pal 10. I've added that one to my ever growing to-do list. NED lists not one galaxy in my field. Not surprising as this is one of the most heavily obscured areas of my sky. 14" LX200R @ f/10, L=4x10' RGB=2x10', STL-11000XM, Paramount ME Rick -- Prefix is correct. Domain is arvig dot net |

I attached the wrong files -- twice. I need more sleep. Here's the correct ones.
