    Re: Southern sky CN photo puzzle
    From: Frank Reed

    If anyone is still interested, here are some images to help identify stars in the original photo compared with a Stellarium simulation. It takes a little back and forth viewing to spot these things, but with a little time they jump right out. I find the shapes of Canis Major and faint Grus unusually easy to spot in the original and in the simulation. Next step: estimate altitudes and then do a plot using the South Pole as the AP, Dec (S) as Hc for each star, and Hs values estimated from the photo, and SHA/GHA as a pseudo-azimuth from the pole/AP.

    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.
