 One can do it with a confocal, but other than double exposure how does one do
 it on a light microscope?

Marge,

You could use a microscope with a standard epi-fluorescence system 
(containing a lamphouse for mercury or xenon bulbs) and order a dual-bandpass 
filter set that has the proper excitation and emission filters for the two 
probes you're interested in.

A good source for the filter sets and cubes: Chroma Technology at 
.

Best,

Bob
