The coordinates in the image-manager are now incompatible with the coordinates of the objects.  Is it possible, to go back with the objects to epoch 1950.0 ore what can I do?

Ouch! That's a good point. There isn't a way to return the objects from 2000.0 back to 1950.0, but I can add it pretty easily (or create a script to do so). Also, I should have the option of changing the epoch of associated images (although while this will associate the images with the objects, they will be out by 5' - 10' or more, since all images are epoch J2000.0).

Let me see if I can do that today.
