Just working through my captures from that evening. This may be my best so far, though I'm still a little disappointed that I'm not getting more detail. I'll see what else I get as I work through the others.

127 Mak, Celestron Ultima 2x barlow, SPC 900, stacked from 3600 frames at 1/10th sec.

I would be happy with that too James, but I know what you mean. Its a big learning curve and am sure more detail will come.

I also have a 127 Mak, but havent attempted imaging yet, though have Gstar camera to use when I get around to it.

Good effort James,

brightness and colour are prob down to individual,

but i would say this would be improved by added bit of brightness either by streching histogram or levels a little,

more practise, better focus and or conditions and u will get some better results, keep at it, how many many frames did u stack ?

I agree on the brightness. I've been working in the processing of all of my captures from that evening and I definitely think it benefits from being brightened a little.

Focus is a toughie. I have a Y mask that I use to try to get a good focus on Arcturus, but the "cross" is very faint and difficult to work with in the camera image. I've been wondering whether it's worth making a 10mm ep parfocal with the camera and focusing using that. Of course it would also help if the seeing were better, too. I guess it doesn't help that Saturn is relatively low in the sky now and conditions here haven't been stunning for a fair while. I tried with a 3x Tele Vue barlow later the same night and Registax couldn't align anything worth working on.

For this image I stacked around 1800 frames, which was just over an 80% cut-off limit for Registax.
