Thor’s Helmet

The amateur astronomy community is pretty excited at Mars lately – it’s nearing its closest approach to Earth right now, and this one’s even closer than usual. That means some of the best viewing and imaging opportunities for the Red Planet you’ll ever get. When the skies clear and the atmosphere is still, it’s an…

Had a few hours of clear skies last night, and captured a globular cluster I hadn’t imaged before: M92. It’s a pretty one, and I’m surprised it’s not more popular. It’s in the constellation Hercules, and I suspect it just gets overshadowed by its even more spectacular neighbor, M13. Globular clusters were enshrouded in mystery…

There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on.
