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…

If you look at the constellation Orion in the winter night’s sky, the center of Orion’s “sword” is not a star at all – it is the brightest nebula in our sky, M42 or the Great Nebula of Orion. Sitting right on top of it is technically another nebula designated M43, and above that is…

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.

In these short summer nights, I want to take advantage of every moment of darkness. Right now, the galaxy M100 is up in the hours before midnight, and the “Tulip Nebula” – formally SH2-101 – rises just as M100 sets. So for this past week, I’ve been imaging both objects. But no more clear skies…

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.

11 light years away, the “bubble” itself is formed from the solar wind of the large, hot star inside of it. Imaged with narrowband filters.
