NavList:

As a complement to my previous post, and given the picture forensic details published afterwards, I do not rate this artificially derived picture as quite reliable to establish some kind of astronomical position from it.

From recent experience, the less unreliable data we can extract from it seem to be Deneb and Schedir (Alpha Cas), both being sufficiently close and symmetric from the picture center and sufficiently high to be almost unaffected by refraction.

With unrefracted distance between them equal to 38.0°, I could derive Deneb Height at 29.5° and Schedir Height at 36.0°

With the respective Azimuths being 7° for Schedir and 320° for Deneb - both reasonably apart then - I would rate the resulting Latitude as accurate to +/- 1.5° (1 sigma) and the Longitude as accurate to +/- 1.0° (1 sigma).

If picture taken on Nov 15th, 2023 at 00:30:00.0 UT, then I get a fix at N03°10' / W060°50' , i.e. well inland and somewhere in extreme north Brazil.

Frank, how do you solve this ?
