Not a particularly bright or noticeable cluster of stars. Partly because it's in the midst of the many stars of the Milky Way. Still it's a nice relatively compact cluster that looks nice in a  8"-10" telescope. It's about 5000 light years away, a little further away than many of the better know clusters. This one is relatively small (11 light years in extent), few members (about 90), and young  (~90 million years old). There is an unusually separated group of about a dozen  stars forming a rough pedestal below the main cluster. They are part of, and born along with the main, roughly rounded group above it. Visually, it's about magnitude 8, and is 15' in extent. So it can be detected as a non stellar, slightly more concentrated patch of stars in the Milky Way. Nearby to the NE is open cluster M11 which  is much more noticeable and interesting. M26 is best seen in the evening during June-July, or later at night in September.
