I have a major processing error here. Forget this image, I'll have a corrected version up once I get it finished. Seems I used LRBB processing, using the blue frame for green as well as blue. Also I say f/5 when it was taken at f/10. Two crashes!
King 5 is an open cluster in Perseus. The King catalog of star clusters is small. There are only 26 members and #3 is missing or a duplicate of NGC 609, depending on who you wish to believe. Nearly all King clusters reside in a narrow band about 50 to 60 degrees North declination and are in the Milky way running from about 23 hours R.A. to 3 hours. So they are in a rather small area of the sky. It appears King made three searches for previously unknown clusters as the catalog runs from 0 through 24 hours, then does so again, then does so again. Each time picking up less obvious clusters. Some may not even be true clusters. One is actually well below the celestial equator. It must be the outcast member of the group. Anyway I happened to need something in the only clear spot on the sky one night and this was the object. Not needing a lot of exposure time I started to image it. The sky clouded over then cleared then clouded then cleared. With the poor sky I just kept imaging and ended up with my normal exposure time but it was visible only about 20% of the time. The rest of the time I was seeing nothing but clouds. So this image doesn't go very deep compared to my normal images but is rather pretty. The cluster is estimated to be about 6000 light years from us. Distances to such clusters is not easily measured so this is only a rough estimate. Like all King clusters it is made up of faint stars so not a cluster to see visually unless you are using a 20" or larger telescope.
