Star Clouds Near B86 and B90
These two dark matter objects in Sagittarius are among the most distinct of their type for their size. I find these fascinating to look at with both binoculars and with a telescope. The film camera, however, records the vast clouds of stars surrounding them far better than any optical instrument that most folks will ever own. Many thanks to Dean Kettelsen of the "small" mirror lab at the University of Arizona, who first pointed out B86 (on the right) to me. He called it the "hole in space" and I agree. When viewed through a telescope, that's exactly how it looks!
