M13 Globular in Hercules
(200 words excerpt, click title or image to see full post)

Another night of autoguiding fun and games. This time I royally messed up. PC could talk to my CGEM mount, could clearly see guiding images from my Meade DSI-C with no bluescreens. However, no guiding could be done. Tried to figure it out for several hours only to realize when packing up that I had not tightened the RA lock well enough on the mount. Utter silliness. Anyway, NEXT time I'll be set.For now, here's an image of M13. It's a combination of 10 two minute exposures at ISO800 and ten two minute exposures at ISO200 for the core, merged in HDR software.
