Horsehead Nebula

Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…

Imaging deep sky objects from a suburban driveway forces one to find ways to deal with light pollution. Light pollution is the enemy of astronomers – but in reality, there are ways around it. Some of the most beautiful objects in the cosmos are called emission nebula. They are clouds of gas, often where new…

A lot of things have to come together for a good image of the planets. The air needs to be as still as possible, the planet you’re imaging needs to be as directly overhead as possible, and the planet itself should be as close to the Earth as possible. And then, all your equipment has…

Granted this is only a portion of it, but for the life of me I don’t see a pelican in this thing. But, it’s still pretty. I processed this object two ways: using the “Hubble palette” that maps red, green, and blue to Sulfur, Hydrogen, and Oxygen emissions (that results in the pretty blue one)…

M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…

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 –…
