Thanks Pat; I had got frustrated with the mount, so I just did a one star alignment, and tried a quick bit of imaging. A few nights earlier I got a few subs at 180 secs. If and when I get the beast working properly I
should manage 400-500 secs, which is a bit more than the sky here will
permit anyway. The M83 repro is 14 items back on this page.

There was quite a gradient on this image Cam, caused by stray light, so,
as I still haven't come to grips with gradient removal, I just hid it by
darkening the background. I'm in more or less the same boat as Leon,
having given up on trying to get my head around anything more than the most basic processing.
