Description

What can we do in clear nights with nearly full moon: image bright objects such as globular clusters. M 92 is more concentrated than it's more often presentated sibling, M13 wich both lie in the constellation of Hercules.
This image is the first globular cluster I'm not taking for test purposes and I spent approximately 6 hours for imaging. Seeing was not as good as predicted, resulting in fwhm>4", maybe due to some wind.
