SPX350 F39.1, PGRFlea3, Baader RGB filters.

Average seeing predicted but it looked good as the Airy disc of the star I collimated on was pretty good. I could see the Hygens crater below Syrtis Maj in the preview so I was very happy. I combined 2 sets taken 40mins apart, I should have taken 4 sets in a row to combine with WinJupos to extract extra detail but just forgot for some reason.

I managed to get the sharpest image yet with a little more detail, I feel the scopes limits can be pushed further but the seeing is the obvious limiting factor.

I managed to resolve the crater at the North end of Syrtis Major which I have not done before and few ever manage - I show a comparison with HST image of the area. I put together a GIF of the 3 sets before cloud came in.

Combined 1147+1231hrs UT
Softer version 1231hrs UT
Hubble comparison with my image.
GIF-1147, 1231, 1313hrs UT

Thanks for looking, John.
