There! This will fix the rotten-ring syndrome! Would you believe this is straight outa registax without any wavelett work at all?
Conclusion: This toucamming is a piece of cake....all you need is excellent seeing & a driven scope...the rest is pure logic. Just don't use an achro refractor 'cos it will drive you mad!!
Thanks for trying Mike. I'm using a baader fringe killer filter, without it I get even greener rings. I'd be real interested if a IR/UV cut filter would solve this problem.
Ving, just waiting for decent weather...maybe one day we'll get some :-)
Last night I stayed up for a go at saturn, and found some really nasty seeing, probably jetstream related. I'm determined to keep trying, hopefully a good night will come along soon - it's prime time on saturn for the next month or so.
