Don't forget that when you magnify the image with a long lens you are also magnifying any pollution or atmospheric distortion as well.

'Quite far' and a 1500 mm focal length (30x) could well mean that you are running into atmospheric pollution/distortion problems. I am all too familiar with it with both lenses and telescopes when photographing/looking at ships over water. This can be so bad that even at 200 mm focal length the resulting photos are useless, yet when looking with the naked eye the effect is not apparent.
