M14 and M9 (also M80)

M14 is a globular cluster (apparent magnitude +8.32) containing several hundred thousand stars and located approximately 30,000 light-years.  Meanwhile, M9, also a globular cluster (apparent magnitude +7.9) containing approximately 120,000 stars located approximately 25,000 light-years from Earth.  Both of these objects were taken when the moon was just past full but the weather was clear so I decided to go out and collect images.  The results were OK considering the moon was out but M14 was clearly better. These images also represent the 30th and 31st Messier Objects I captured with the ED80.

Addendum:
Also imaged M80 the same night.  This was a stretch from my home (The Happy Frog Observatory) as M80 was around 25 degrees altitude and and just above the tree line for a 10-minute interval.  I need to go somewhere else to get a better image, however, I managed to get 3-45 second sub-frames.
