The Moon

This one’s also known as the “Silver Sliver” Galaxy, or more formally NGC 891. It’s about 30 million light-years away, well beyond our own local group. It’s thought to be quite similar to our own Milky Way! What I really geek out on, though, is the wider views here – there are so many other…

This is planetary nebula PK205+14.1, but its common name “The Medusa Nebula” rolls off the tongue a little better. About 1500 light-years away within the constellation Gemini, you’re seeing the gas blown off by a small star that ran out of fuel, and blew up into a red giant – later to end its life…

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…

Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner! Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.

Deep-sky astrophotography is the ultimate hobby for nerds; it combines endless tinkering with highly specialized technology, exploration of the cosmos, and constant challenges, achievements, and learning. But, could this hobby be automated to the point where anyone can do it? Products such as Stellina and Unistellar promise to deliver an experience where you can plop…

This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…
