In another forum we were considering a wide field pic that a member had made of the MilkWay,
we identified a little fuzzy 'blob' in the right place for M31, extending a little to the right and left,
and I proposed that if there was an alien on a planet circling a star in M31 pointing a camera this way (wave !) we would be about - "here" - and I put a red dot about 2/3 or 3/4 of the way out from the centre on that fuzzy blob in that post.
But then I thort
(a) would we be seen edge-on like M31
(probably because M31 is seen close to the plane of the MilkyWay [ ?? ] )
(b) would we be seen to be to the left or to the right of the middle ? (?? I give up ! no idea!!)
We must be on one side or the other else if we were line of sight with the middle then M31 would be in Sagittarius ? would it ?
The camera was a regular terrestrial one, on a tripod doing a 30sec exposure, in the northern hemisphere (UK) so I dont think we have to do inverting and newtonian and multi whatsits things !
