Thanks for the feedback Jeff and Nick.
I often find it tricky to judge brightness on a posted image so I will retry the two dimmer images.
Jeff, I have found that many scopes can give you decent images if you get good seeing, reasonable collimation and can manage thermals. Smallish scopes are less trouble to put out more often. I have previously posted images with a ETX-105, a C6 and now a C8. Unfortunately good seeing is not common in many locations so you have to try often as indeed I see you do. This seeing was just on the good side of moderate.
As I have brightened up Saturn as per your suggestion...it might show it s flaws clearer! and I put a location guide next to Mars for anyone who wants to stretch their imagination.
