A Harvest Moon Eclipse

With this month's lunar eclipse favoring the east coast of the United States - the Moon well above the horizon at mid-totality before midnight on a Sunday evening - I was hoping for some clear skies so that I could put the 80mm Vixen through its paces. However, the weatherman had other ideas. I kept checking every 15 minutes or so once the eclipse had started shortly after 9 p.m. but conditions were overcast.
Finally a little before 11 p.m. I saw one or two postings on Facebook from folks who were saying they could see something. I stuck my head out the window and sure enough the clouds had broken up enough to reveal a coppery Moon hanging high in the eastern sky. While not practical to set up the Vixen I grabbed the camera, telephoto lens, and tripod and headed for the back yard.

The view was fantastic - a fairly dark eclipse I would say, with a color range from darkish red-brown to the copper colored edge nearest the limb of Earth's shadow. I really felt at home with the DSLR this time in manual mode, firing off a range of photos and adjusting them based upon the near instant feedback displayed on the LCD. The clouds continued to try to take back possession of the evening but not before I was able to secure a few memorable shots.
The one thing that I have to say - I am so tired of all this "Super Moon!!" junk in the papers and social media. And the fact that we had a "super" Moon undergoing eclipse - well one would think that it was as rare as a Venus transit. It was a great eclipse to be sure, but the slight difference in the Moon's size as it was near perigee was more of an academic footnote than of any real visual consequence.

Urban List: M13

Observation
Object: NGC 6205 - M13 - Great Cluster in Hercules, The Wall
Deepsky Catalog: NGC 2000
Log Type: Urban Sky
Date Observed: 9/8/2015  03:15 UT
Object RA: 16h 41.687m
Object Declination: 36d 27.58833'
Object Type: Gb
Constellation: Her
Magnitude: 5.9
Size: 16.6
Locate Method: Star Hopping
Observing Location: Tomney Residence - Front Driveway
Object Rating: A
Primary Equipment Used: Vixon ED80sf (80mm f/7.5)
Power/Magnification Used: 30x
Transparency/Seeing: Deepsky Clear / Deepsky Mostly Stable
Detailed Observing Notes: Nice wide field view of M13 including the two neighboring ~6th magnitude stars (SAO 65508 and 65481) - the former actually exhibits some orangish tone in the view. M13 appears symmetrically round and pretty even in illumination, no striking brightening as at the core which was a little unexpected and possibly due to small aperture. Size is about 4' and there is no resolution, even with averted vision. Very nice object even if only 80mm of aperture in play..
