Space Jellyfish!
This is IC443, commonly known as the “Jellyfish Nebula” for obvious reasons! IC443 is a supernova remnant about 5,000 light-years away. This is a false-color, narrowband image consisting of a total of 20 hours of exposure time.

Imaging the planets requires completely different techniques and equipment than deep-sky stuff, and it’s something I’m not really good at yet. What matters the most is the seeing conditions – how stable the atmosphere is. A big part of taking good planetary images is just having the perseverance to get out there whenever the seeing…
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,…
I’ve imaged this one before, but for whatever reason I picked up way more detail on it last night. Part of it’s a better camera and better tracking on the telescope mount, but I think conditions may have just been really awesome last night. It’s not normal to have this many good nights for astrophotography…
As we enter summer and the Earth starts pointing us back into the plane of the Milky Way and its many nebulas, we’re nearing the end of globular cluster season. M5 seems a fitting one to end on this year; there’s nothing terribly remarkable about it, other than I think it’s pretty. It’s located about…
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
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…
