SVN commit 894589 by asimha:

Fixing bug #164493. The trouble was that the coordinates of the object
were not refracted in SkyMap::checkVisibility(). The result was that
some stars that were supposed to be visible in the field of view were
not considered to be so at high zoom levels.

There are a lot of other refraction-related problems to investigate
into as well!

Will backport to 4.1
