Object name: BERKELEY034
Berkeley 34 is a distant, faint open cluster in Monoceros. It's brightest star is about magnitude 13.5, next brightest 14.1. Most are magnitude 16 through 18. I suppose a large Dob will show a glow with a half dozen of stars on top of it. WEBDA puts it at a distance of 24,000 light-years and gives it an age of 2.8 billion years. A paper on it, however, says it is only 2.1 to 2.5 billion years old. The cluster is located about 180 degrees from the center of the galaxy. That puts it on the outer edge of the galaxy. While there's not a lot of dust that direction but at its distance, it is estimated to be reddened by about half a magnitude. Its age plus the reddening accounts for its lack of blue stars. Only the brightest, 13.5 magnitude star shows blue. The rest are white to red. This makes me question whether that star is a member or just a foreground star.
