Apologies for the not so good composition but it was really cold there! Yes, within a few hours, we went from tropic Hawaiian temperature of 25 deg C to -5 deg C at the summit.
I could not handle my camera (Canon 40D) with my gloves on, so I had to take it off and my hands went numb with the cold! I could not feel the buttons on the camera, and later I could not untwist my tripod even. I think it's time to move to 1D4 for the larger buttons.
Anyway, here are some pics that I managed to take (vantage point at Canada-France-Hawaii Telescope) -
