I don't know how good the optics (and alignment) are, on the microscope you ordered. You'll find out quickly enough.

If there's color fringing, or the field isn't flat (edges focus differently than the center of the field), can you return it?

PS -- I did a quick look for alternative stereo microscopes, and found things like this:

GreatScopes Microscopes: The Achiever Stereo Microscope

for appreciably more money.
