The good spell of weather under the full Moon continues. Not much imaging is possible so I'm concentrating on the bright springtime globular clusters.

And here is te biggest and best of the lot: M14 The Great Cluster in Hercules. This pokes over the tree line at the Curdridge observatory around 11pm and I can imaging it happily until dawn starts to interfer at about 4am.

Of course, I don't stay up all that time - I leave the scope to it and get some sleep. This is about 65x180s exposures with the unbinned Atik 490EX CCD camera on the Skywatcher 200 Newtonian.
