I just went up for a couple of hours this evening; I'm acclimatising to the altitude again as it's been a long time since I was last on Mauna Kea. Unfortunately for the photographers up there the sky was absolutely clear, not a high cloud in sight and that means the sunsets tend to be quite boring, at least to those that have seen the odd one before! Still, clear skies mean excellent observing, so the astronomers will be happy tonight.

As I've mentioned on the odd occasion in the past, my camera is very poor in low light conditions but the view from Hale Pohaku at the 9,000 foot level when I came down was stunning - it was the Milky way just about to set in the west. I'm fairly certain this is the Galactic Centre as it's about the right time of year for it to be setting just after sunset. The lights at the bottom left are from the Visitor Center where the volunteers were already showing the night sky to tonight's visitors.
