Hi Matty,
Thanks very much
I resampled the image at 2x during stacking.
There is a moon just above the planet (close to touching it)

I captured this Moon moving in relation to the planet throughout the night but the seeing was terrible on the earlier images. I think this might be Rhea. The image was taken at 2:20am on 25/01/2008 AEST.
Have fun,
Doug
