Bill,
Improving nicely! As Dave said, it looks like field rotation alright. Perhaps try going for a few seperate images of say 1min exposure and stacking them afterwards outside of the DSI software. With the LX90, you should be able to go to 1min exposures at the very least without geting field rotation. I recently took some 2min exposures of M57 with my LX90 in alt-az mode & the 300d slr camera and had only very slight field rotation. In your case, the DSI has a much smaller chip and so should have no trouble with the aforementioned exposure times.
Clear skies,

I have the Philip's Deep Sky Calendar on my study wall, and your M57 and its M57 are not a million miles apart, July section. I would love to have the knowledge, the skill, and the equipment to achieve even half the mark. Super pic!
