Frank,

Thanks for your last explanations :

Then in the vicinity of Tromsø accessible by road and within 1° of Latitude, the best I can find with an almost vertical cliff into the sea in Azimuth close to 250° would be the Hamn Lighthouse ...

Is it really too much luck because its Latitude is N 69°24.8' (vs. N 69°23' in case (1) of my last post. )

I simply cannot believe it ... So where is the picture taken from actually ?

As regards the Longitude determination (+/- 45°) , you got it from the Stellarium time, did you not ? If so I cannot compete at all here ...

Or which other method did you use ?

Kermit

PS : Thanks again for this interesting drill ...
