peculiar clouds (Blue Mountains)

Peculiar clouds slid over the Carr Astronomical Observatory as we set up on the Observing Pad.

I pulled the radar imagery from ADDS. It looked like we were in a funnel: clouds pushing down from the north-east while clouds pushed down from the north-west. But, we were hopeful...

At one point I noticed spectral colours, like in a rainbow, on the lower edge of the linear clouds. Clearly water, caught in the golden sunlight, refracting the photons.

Canon 40D, 18-55 EF-S lens at 18, 1/640 seconds, f/4.0, ISO 1600, tripod mounted, RAW, slight processing in Canon DPP.
