    Re: Photo challenge: what is your latitude?

    David Pike: If Stellarium Desktop isn't working properly for you, you should try the "web app" version here: https://stellarium-web.org/. It's not essential for anything, but it's nice to have another option. :)

    I think I've waited long enough on this one, and I have already said it's difficult. It's time for a few clues. First clue: there are three significant navigation stars just barely out-of-frame. So useful they would be if they were in-frame! One of the three is off the left side of the image. The second is off the the lower right, either hidden by the horizon or lost in the low-altitude extinction. And the third significant star is just off the top of the image. Second clue: in the "good to know" category, I can assure you that the field of view of the image is not unusual. It's about 70° wide and 40° tall, so you don't have to worry about any telephoto zoom or weird fisheye wide-field effects. Third clue: an astronomy phrase that you might know already, or you can chase down if you don't: h & χ. Also see the snippet of an old star atlas below...
