This comet will reach its brightest point a couple of weeks from now, but the skies were clear this morning so I figured I should go for it while I can! The tail’s not as pronounced as I hoped, and processing is a bit sloppy in a couple of spots. But hey, it’s a comet. Pretty.
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…
This is the Helix Nebula, sometimes also called the “Eye of God” or the “Eye of Sauron”. It’s a planetary nebula, formed by a star blowing off its outer layers of gas before collapsing into the white dwarf you can see at its center. This is thought to be the ultimate fate of our own…
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…
This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…
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…
Hope to revisit this under better conditions in the future; but this came out OK considering a bright moon was out the night it was taken. The Pinwheel Galaxy (M101) is near the end of the handle of the Big Dipper in the sky, although physically it is tens of millions of light-years more distant.
