The Whale and the Hockey Stick

This dim nebula in the constellation Perseus has no name, apart from its catalog numbers NGC 1491 and LBN 704. I think it deserves one. It reminds me of the Bubble nebula – if you look closely, you’ll see a “bubble” at center being created from the stellar wind of the hot star that is…

Here’s another galaxy with no nearby neighbors, and no catchy nicknames either: NGC 3344. It’s about 22.5 million light-years away within the constellation Leo Minor. Although it doesn’t get the love it deserves, it’s a glorious face-on barred spiral galaxy that’s about half the size of our own Milky Way. Explore the space around it,…

This comet will reach its brightest point a couple of weeks from now, but the skies were clear this morning so I figured I should go for it while I can! The tail’s not as pronounced as I hoped, and processing is a bit sloppy in a couple of spots. But hey, it’s a comet….

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…

Narrowband image of the cone-shaped absorption nebula in front of the brighter emission nebula in this interesting region of the Christmas Tree Cluster, about 2,700 light-years away.

Combining 25 hours of data shot over two years, here’s M64. It’s an odd one, with counter-rotating disks that seem to have funneled all that dust in the center there. They think it’s the result of a merger of two galaxies that were spinning in opposite directions. Located about 17 million light-years away, in the…
