Thanks Trevor. Spending a bit of time on this to get a feel for my gear.

No wonder I don't like planetary imaging 
One of the Planetary guys will be along shortly to tell you how they got rid of them 
I think it is caused by Wavelettes  |
It certainly can catch you by suprise but believe it or not, it's actually "good" to see others have experienced this before so I am little at ease in that it may not be a one off due to a fault in my optics.

I recommend the next step to be; pulling the trigger on a webcam if you truly want to get serious about planet imaging.

I love your choice of words : wringing -and yes I want to wring every last drop out of it !!
I want to make sure my basic skills are up b4 I decide to pursue more detail - that US dollar is looking attractive at the moment $$$ - just need more $$$.

My main concern was whether it was to do with the setup of the optics or the DSLR operating in such an unusual manner. It would be really dissappointing to get all excited and go to a good CCD only to find the same problem lurking around there. Will need to investigate more. Good luck Malcolm!!
