It's a standard Celestron C-11 on a Losmandy G-11 mount, very carefully
collimated. I used a 3x Televue Barlow, projected to about 3.5x giving about
f/35. The camera is a standard ATIK-1HS using Astronomik RGB filters.

Hi all,

Far and away the best Saturn image I've ever got! Good seeing and
painstaking collimation were the reasons.
