Cone Nebula
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.

Officially called M63, this spiral galaxy about 30 million light-years away is part of the same group as the Whirlpool Galaxy.
This is NGC281, or the “Pac-Man” nebula. I think it’s one of those objects that might look a little like its name if you’re viewing it through a big telescope in a dark sky, but takes on a totally different character in long-exposure, narrowband images such as this. This is a total of 13 hours…
This image contains a few things! At the bottom is the Cone Nebula, at the upper-right is the “Fox Fur Nebula”, and in the middle is the “Christmas Tree” star cluster… you have to flip the image upside down to see that one. It’s a gorgeous region of active star formation in the constellation Monoceros….
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…
M13, the great globular cluster in Hercules. You can see some of its interesting neighbors, including the galaxy NGC 6207 in the lower-left. While M13 itself is 25,000 light-years away just above our galactic plane, NGC 6207 is 37 million light-years distant. About halfway between the two, the galaxy IC 4617 is also visible –…
Formally NGC1570, the “Northern Trifid” is a combination of an emission nebula (the red parts, which is ionized Hydrogen emitting its own light) and a reflection nebula (the blue parts, which is starlight reflecting off dust.) You can also see hints of the dust surrounding this area, which is difficult to capture under the light-polluted…
