Steve, Bernd. List,

 What microscope do you use to view meteoritic specimens? I am looking for
recommendations for purchase.

Thanks.

All the best,

Bernd,

I just spent a while at the microscope, (first time since March 26,
shame on me), and I'm seeing exactly what you're talking about. The
vast majority, (app 90%+) in my slices anyway, have the same
orientation. Another thing I'm seeing that's really neat is that the
bars in the barred olivine chondrules seem not to be running in a
straight line as I'm used to seeing, but rather have a swirl, again
following the shock orientation! Gotta get more time at the 'scope.
Hope to post a link to some images later.

thanx,
Steve
