Description

A quick-shot on the most standard object in spring - M13. Initially thought just to test the camera orientation, I noticed a seeing in 5-min-subs of 1.4 arcsecs. It didn't last like that but the overall FWMH of this picture is in the range of 1.8 arcsecs. For the core itself, I used only 3 subs averaging 1.45 arcsecs resolution. Of course, the short integration time sacrifies depth.
