Draco's Nose

I took the 100mm f/6 out last night for a short session. After a quick look at Jupiter (with Ganymede on one side and the other moons all grouped on the other), Albireo, M29, M27, and M22, I turned the scope to Draco's nose.
First, I found NGC 6229. This is a globular cluster in Hercules just south of the nose. Appearing much smaller than M13 or M22, and not nearly as bright as M92 just to the southeast, still NGC 6229 was not hard to find. It sits next to a couple of stars and the three objects together make a nice equilateral triangle. I could make out no individual stars in NGC 6229, but given that the globular is about 100,000 light years away, much further than M13 or M22, that's not surprising.
If Draco has a short nose, Al Rakis or Mu Draconis is it. It's a nice double star of about equally bright components that was split at 75x through the 100mm. It looks a little like Gamma Virginis---two tiny headlamps---only appearing a bit further apart than that system right now.
If Draco has a long nose, 16 & 17 Draconis is its tip, also a splendid view. 17 is a double, so the whole is a triple system resembling Mizar and Alcor somewhat, but closer together. 17 was also split at 75x.
I will definitely go back to these doubles soon.
