This is timely as I just scanned this frame a couple of days ago, although it was taken back in February or March IIRC.

Fuji Provia 100
Pentax 645N 75mm F11 1/15 (used gorillapod)
Technically, I think this fine image is outside the rules, because IIRC the shot needs to be taken during the appropriate time period.

But I'm certainly not complaining.
