Heck yeah it is!  Thanks for the idea.

Hmm, I don't think it's much of a problem, since images are only loaded into 
memory when the object is actually on screen at a high zoom level, and the 
memory is freed when it moves offscreen.  If there is a delay caused by 
reading the image from disk, that might be an issue, but I don't expect it to 
be a problem.

I'll look into redoing all of the Messier images using this method, unless you 
(Glenn) want to add Messier objects to your list?
