HOW TO FIND IT:
Draw a line from Epsilon through Lambda and continue. M25 is about 6 degrees north of the teapot's lid in Sagittarius.
WHAT TO LOOK FOR:
M24 is an open cluster with a somewhat oval shape. Look at it with the binoculars, then with a telescope look for another cluster in the heart of M24. This is NGC 6603 and it shows up as a dense concentration within M24. NGC 6603 shows up with a formation of a very small, tight knit “V.”
M25 contains a variable star. U Sagittarii varies in brightness over a 6 day, 18 hour period. It will take an experienced observer to discern this.
