I was thinking the same thing. No microscopes here! I like seeing these. The arrangement is pleasing and the light is interesting. I like that warm reddish glow on the near side of the objectives. I keep looking at the shot. It's just fun to look at.

Doesn't this violate the "no microscope pics" rule? He he he.
