Did anybody else have a crack at the Lat & Long? I got Lat by assuming the outer edge was the horizon and counting in until I got to Polaris at about 42N. Then I configured the picture on ‘Navigator’ for 42N 000E/W at 04:00 UT on 25Dec2025. Next, as the picture would be rotating about Polaris with time or longitude, I just kept altering the longitude until Ursa Minor looked in the correct place. Problems encountered were that ‘Navigator’ shows the picture using azimuthal grid whereas the jewelry shows equatorial grid. Also, one is shown from inside the Celestial Sphere looking out whereas the other is drawn from outside looking in, so you’re faced with a mirror image effect. DaveP
