"The final result! At this point I realised I made a vital mistake. That is; I did think about it but I just came to the wrong conclusion. The starmap I used is a mirror-image of the real sky when you look up (they always are). I thought this mirroring would be undone when I lifted the whole thing up to the ceiling, but I didnt think this through enough apparently.. Instead of 'un-mirrored' it is now 'double-mirrored' *cry.. The constellations are in the right position with respect to eachother, and the distances are right, just the whole thing should be flipped.."
