Iuppiter sese obviam fecit

Yes, I know there is nothing technically interesting about yet another grainy picture of the Galilean satellites. But…

Callisto, Europa, Ganymede, Jupiter (and Io lost somewhere in transit).

…that’s taken leaning out of the kitchen window, without doing anything clever, using the battered camera I throw in my bike panniers and take to work regularly. It’s not even a very interesting camera – no fancy lenses, no high-sensitivity sensors – indeed, it’s famously terrible in low-light conditions, which I suppose by definition includes “photographing the night sky”. But all it needs is a quick crop and an inversion to show them up clearly.

The relentless march of technology has some unexpected side-effects. I don’t think I ever really though I’d be able to do this on a whim, and for all that it’s obvious it’s not difficult, it’s still a bit of a thrill.
