HOW TO FIND IT:
M55 sets off by itself, compared with the other Messier objects in Sagittarius that come in chains or groupings, but it is a wonderful deep sky object that you need to take a look at.
Drawing a line from Delta to Zeta in the teapot of Sagittarius and extending it almost that same apparent distance gives a rough location. Another set of guide stars are Sigma and Tau in the teapot's handle, but these guides give no idea or how far from the teapot area M55 is found.
WHAT TO LOOK FOR:
M55 will have the appearance of many globular clusters, looking like a bright hazy patch. A distinctive feature is the single conspicuous bright star that the observer ought to try to locate.
