Lenticular by Night
Cloudy nights aren’t always a disaster for astrophotographers.
But on Mar. 9, 2013, near Mt. Hood in Oregon, he took the unbelievable picture above.
I know, right? That’s a lenticular cloud, so called because they’re shaped like lenses. They’re fairly common near tall mountains, where moist air flowing around and over the peak condenses downwind of the mountain. The air is always flowing, but the spot where the moisture condenses is stationary, so it looks like the cloud is hovering.
Some lenticulars are huge and dramatic, looking just like UFOs (and because they hover they’ve been reported as such). Others are smaller, and may only be rounded on the upwind side, trailing away downwind. I see that kind all the time here in Boulder, with the ragged tops of the Rockies to the west.
Ben’s shot is incredible. Mt. Hood and the cloud dominate the shot, but if you look at the full-res picture you can see some stars dotting the sky; I could see the constellations of Cassiopeia to the left of the volcano and part of Aquila to the right. He mentioned he took this shot at dawn, so I knew he was west of Mt. Hood facing east, making the stars easier to identify.
Taking great pictures takes a lot of preparation and experience, but sometimes being lucky helps. Even if that luck is bad—and clouds block the star shot you want—you can still make some good of it.
