HOW TO FIND IT:
Look south of Zeta Ophiuchi.
This is another good time to use the guide stars we used for M10 and M12. If you recall, we used the head stars of Scorpius (Pi, Delta and Beta) to direct us to the area of M10 and M12. You should be able to see four stars in a row,
irregularly spaced. These are Zeta, Upsilon, Epsilon and Delta. To find M10 and M12, we continued beyond these four stars, but this time, we want to move back toward Scorpius.
If you still have difficulty, sweep between Zeta and Theta Ophiuchi.
WHAT TO LOOK FOR:
M107 will be fairly loosely packed.
