I saw this gallery of snowflakes on weather.com this morning and thought
that overall Mark's photos are much better.

What is interesting is the technique used in that case.
It's indeed a micrscope. You can see the last three photos showing the
setup.
I suspect the setup might be responsible for some uneven focus over
the field of view. It looks like the DOF is very shallow.
