It seems yonks since I set up the LCD microscope for a session.
As a frost was forecast for this morning I thought it would be different to see the frost close up instead of pretty photos of frosty plants. To have the longest possible time to adjust the microscope focus before any frosty object thawed I set things up in the unheated greenhouse. The microscope being powered by a 5V power bank. Even so the crystals started to melt almost immediately. Anyway here are a few captures at varied magnification:
There were a few crystal spikes but they melted too fast to get a decent photo.
