I posted this picture of Gemini with UKIRT in the background the other day but since then I had a little time to improve it while at sea level. Working at altitude often means your brain operates at somewhat less than 100% efficiency! Click on it for a larger view.
At around the same time Gemini was opening, the twin Kecks opened as well. The sky behind them off to the west wasn't encouraging especially as that's the direction high-level clouds tend to come from, but in the end the clouds drifted to the south overnight and it turned out to be quite a good night's observing.
