Thanks folks.

Doh.. i did mean the bands around Jupiter (although we have seen the wafer thin ring around Saturn too!).
Thanks for all your replies, as always you guys are a font of knowledge.
I have always been a bit concerned re the collimation of our scope though. We bought it second hand off a disillusioned teen who was more interested in Playstations, and although it came with manuals, i couldn't really fathom out if it was setup properly. Is there a good and easy to understand guide anywhere? Do i have to re-collimate after fitting the Barlow?
When we view Jupiter (for instance) it appears about the size of a small pea with quite vague banding - it is very bright and tends to "soften" the image at the edges. Is this about what we can expect from a 202 dob with a 9mm eyepiece with no filter?
Anyway as always cheers and many thanks for any replies.
