Not sure if macro photos of space rocks strictly speaking counts as astrophotography, but here are a couple anyway. These rocks (and others) were obtained on loan for use during the Science Festival Week.

Part of the Imilac stony-iron meteorite....



Part of the Parnallee ordinary chondrite clearly showing chondrules and the external fusion crust formed by heating when it plummeted through the Earth's atmosphere....
