    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.

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
