The star next door.

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….

Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…

This morning, my cat woke me up at 3 AM, and I noticed it was clear outside. But, the sun would start rising in just a couple of hours, so doing some super-long-exposure shot of a faint nebula wasn’t in the cards. However, globular clusters don’t take long to image, as they are relatively bright…

This galaxy is truly one of a kind, at least among that galaxies we have found. It’s a “polar ring galaxy,” probably the result of an unusual collision that left the core lenticular galaxy surrounded by the disk of another galaxy that it merged with. It’s a small, dim object, and just barely detectable from…

Both on Earth, and in space! While we prepare for a year or two in California, I trained Scopey von Scopington on the California Nebula for a few nights. Pretty obvious how it got its name! This is a two-panel mosaic, consisting of narrowband SHO data for the nebula and broadband RGB for the stars….

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…
