This is a fine large, 109 arc sec, mag 11.4 planetary in Aquila. Magnitude of the central star (very close to the brighter star depicted near the center) is 16.2, however I was not able to capture it. The seeing was rather poor at a Pickering 4, and I think the nebulosity washed out the dim central star. Sketch was done at the EP of a 20" F4.5 at 326X. The location was once again Mesquite Springs in Death Valley, CA. Naked eye limiting magnitude at zenith was 7.9.
