Saturn with Tethys shadow transit

Still got some work to do on this image but here is a capture of
Saturn from last night showing the shadow of Tethys moving towards the
limb (bottom-left of globe).

Good stuff as usual! Nice colour/detail at the pole there, too.

It is a fabulous image! What was the equipment used and post
processing?
Seeing must have been extremely good...

The key one that isn't is how many frames used out of how many taken
and at what repetition rate.
I cannot believe that image is the result of a single lucky strike
(although it is theoretically possible).

Hi Martin,

I'm currently taking around 1000 frames for the R & G channels and
anout 700 for the B. These are quite low frame counts because the
dimness of the planet at this image scale necessitates dropping the
frame rate to 17fps for the RG channels and 8fps for the B. I could
reduce the image scale but I prefer this one to be honest.
