Fig. 12-x :   Mosaic Observing:
 Either with a carefully prepared plan, or using trial and error
for targets of opportunity, one can generate different mosaic
geometries, plot an overlay of the tile pattern over an A&G camera
acquisition frame, and finally arrive at an optimal configuration for 
subsequent use. Centering the mosaic on the target works identical as the 
normal single pointing procedure. 
Note: saving/restoring the corresponding guide star coordinates allows 
one to repeat or finish incomplete mosaic observations 
from a previous observing night.
