Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner!
Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
Well, it was certainly born of fire. This is planetary nebula Abell 39, one of the largest spheres in the galaxy… it’s 2.6 light-years across! It really is that color blue. You’re seeing ionized Oxygen gas blown off by the dying star in its center. Look closely for the distant galaxies in the background, including…
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 image was something of a happy accident – I spent a night capturing narrowband data on M16, the Eagle Nebula (home of the famous “pillars of creation”.) Of course I had to try reproducing the iconic Hubble image as best I could, but the color palette they use results in big, ugly, magenta-colored stars….
Hoag’s Object is the weirdest galaxy I know of; it is a “ring galaxy” – a very rare galaxy type that’s just a galactic core of stars, surrounded by a ring of stars that’s seemingly disconnected from its core. This galaxy has always captured my imagination. Just look at this image from the Hubble Space…
The Horsehead and Flame nebulas, although popular, are really difficult to image together. The clouds of Hydrogen look best using narrowband filters, but the blue reflection nebula below the Horsehead only appears in wideband, color filters. Further complicating matters is the bright star Alnitak, one of the stars that makes up Orion’s belt. In narrowband,…
At the center of this image is the distant galaxy NGC210, 65 million light-years away within the constellation Cetus. It’s mind-blowing that we can capture an image of something so distant from our backyards, given the right technology. It’s also mind-blowing that we’re looking at light that has been traveling for 65 million years, giving…
