    DaveP, on Oct16 you wrote: I tried to place you on prorobably the 14th from the size of the Moon; the time of the shot; and the azimuth of the moon using 'Navigator' which my PC finds easier to manage than 'Stellarium.  I couldn't help noticing that earlier in the evening Saturn and the Moon were almost on top of each other.  However, whilst out doing my 10,000 steps, I got a good view of the Moon around 19:00UTC, and although they would have been well within a 2° perisextant field of view, I never noticed Saturn.  By 23.50 from N53°10' W 000° 32' they were just outside a 2° field of view.

    Indeed, I took that Moon/bubble photo on the night of Oct14/15.  It is possible that Saturn was very near the Moon that night but I still would not have seen it if it were leading the Moon, even by a little bit, given the proximity to the trees.  I was out doing by 14000 steps (not to try and one-up you - I just regularly do 7 miles in the hope I'll be ready for the Fan Dance in Wales (Brecon Beacons) one day) three nights ago and I saw Saturn peeking between the leaves well ahead of the Moon.
