Berkeley 86
Sometimes I wonder why I put an object on my to-do list. This is one of those times.
Berkeley 86 is somewhere in my image. Just where I don't know. WEBDA often misses the right position by several minutes. Checking various sources I find different locations. The one paper I found on it seems to show it about the center of my image which was based on an average of the various positions I found. The paper is at http://iopscience.iop.org/article/10.1086/130853/pdf It has numbered some stars it considers part of the cluster. WEBDA says it is 3600 light-years distant, is 13 million years old and reddened by 0.9 magnitudes. With a paper and WEBDA seeing the cluster I have to assume it is real. All I see are various asterism groupings that change each time I look at it. After a while, even those vanish to my eye. A couple weak dark nebulae appear to wind through the frame. I couldn't find any listed at SIMBAD however. Reproduced at 1.5" per pixel rather than my usual 1" as that would needlessly enlarge the image. Why I took only 1 blue frame is unknown. Since there was no satellite in it that worked out fine. 14" LX200R @ f/10, L=4x10' RG=2x10' b=1x10', STL-11000XM, Paramount ME Rick |
