Thanks to Peter (Hill), Ed, Bob, Roger, Geoff, Terry, Heather and Damian, who along with myself talked to 50+ members of the public about astronomy at the science discovery day today at Rosliston Forestry Centre.
The weather remained dry although persistent cloud meant that solar observing was limited to a few precious moments in the first hour. I ought along my LOMO polarising microscope and folks were excited to look at the birefrigement colour patterns on meteor thin microscope sections and at microfossils in thin sections of fossil-containing rock. Problems with my power inverter left my laptop out of action but Ed’s battery saved the day for the microscope illuminator so that the public could continue to look through the microscope!
The picture below was taken today through the LOMO microscope using my Bresser MikrOkular camera – it shows microfossils in rock thin section. Birefringence in the crystals of minerals in the fossil-bearing rock is evident:
