(poorly) re-setting the target

[Wolfgang Reissenberger]

Had the same problem last night. I will try to find out what happens.

If the target isn't used anymore, then this target change is harmless, but if there's a meridian flip, then it would be used again and can move the image position.

The target is set by the user in the scheduler -- e.g. a certain coordinate, or the solution of a certain fits file -- and the mount has nothing to do with that, at least if we're plate solving to refine the position.  Is there any good reason to reset the target position in the above code link?
