Thanks for the welcome and advise re: registax i will look into that.
James, the Saturn photo is a crop from my Canon 6D, so its not enlarged per se, but will appear so compared to you eye due to the crop.
The camera body was threaded directly onto the back of my eyepiece using a t-ring and adapter so i assume that the image projected to the sensor and that to my eye is the same?
This is the original photo, and it is a bit more representative of the size in the eyepiece.
