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…

Here’s IC417, commonly known as the “Spider Nebula.” Just outside of the frame is a smaller one called the “Fly Nebula,” but my field of view isn’t quite big enough to capture them together! It’s about 10,000 light-years away, in the constellation Auriga. Imaged over 15 hours; narrowband nebula blended with RGB stars.

This is M27, the “Dumbbell Nebula,” about 1600 light-years away. It’s what’s called a planetary nebula – not because it has anything to do with planets, but because early observers confused them for planets. In reality it’s far more interesting. This is what’s left over when a medium-sized star runs out of Hydrogen to fuse,…

This portion of the North America Nebula in the constellation – you guessed it – Cygnus, is a giant cloud of ionized gases where new stars are being created. It’s also pretty. These are both false color images, processed a couple of different ways. The first is the classic “Hubble Palette” that maps ionized emissions…

AKA Abell 1656. There are tens of thousands of galaxies in this portion of the sky; almost everything in this image is an entire galaxy filled with hundreds of millions of stars. Whoah. And they’re hundreds of millions of light-years away. Click and zoom in to explore them all.

There’s a big cluster of galaxies within Virgo; it’s just filthy with them. People usually image a different part of it, but I found another interesting area that’s often overlooked. The grand-design spiral at the bottom is NGC5364; it’s about 55 million light-years away. The annotated image identifies its buddies.
