This was first light with my AT8IN and QHY8 OSC. I hadn't at the time received the extension tubes I needed to place the camera at the correct distance from the coma corrector, so this image suffers from less-than-ideal stars at the corners. Even so, I had to take advantage of one of the few relatively clear nights we had in July here (rainiest on record).
