The Rosette Nebula is about 5,000 light-years away in the constellation Monoceros. It’s the birthplace of the cluster of stars it contains. While it doesn’t look much like a Rose in this view, the false-color narrowband image below brings out more of its structure. 7 1/2 hours of total exposure time, on New Year’s Eve…

Here we have another globular cluster: M53. You don’t see this one imaged too often, but it’s still quite pretty. I’ve never met a globular cluster I didn’t like. It’s one of the more distant globular clusters in our galaxy, about 60,000 light-years away.

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…

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…

M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.

A spiral galaxy almost 40 million light-years away, viewed edge-on. The dust lane in the center of its disk, and central bulge are clearly visible. A couple of its smaller, satellite galaxies can also be seen here.
