Picture of the Week is gorgeous M13 – the Great Globular Cluster in Hercules.
Again, many hours have gone into this one using several different cameras, several different versions of the Hyperstar, and also the Sky90 refractor at f#4.5.
Another object I have returned to time and time again, and yet another object I really need to steer clear of in future as I don’t think I am going to be able to improve on it much (if at all) from my current location.
