Hi Guys,
Thought since I'd dug the scope out I'd give Saturn a go before it left and before the rings close up. When I setup the seeing looked pretty good, but by the time I started imaging was pretty average.
I was over-ambitious using the 4x powermate rather than my 2x barlow and once started couldn't be bothered changing. It seems that the 4x barlow is really pushing the light gathering capability of the 9.25 for Saturn hence greater gain and grain and less frames as I had to wind back to 15fps. The seeing wasn't really there to warrant it either.
All that aside, I've discovered that Saturn has rings :D
cheers,
Rob
