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.

The main galaxies in this image go by the unassuming names of NGC5033 and NGC5005 (5033 is the larger spiral galaxy.) They’re within a constellation named Canes Venatici, or “the hunting dogs.” Look closely, and you’ll spot a few other galaxies – some large but more distant, and some that are just really small and…
Formally this nebula is called vdB93, but more commonly it is a part of the “seagull nebula.” The larger nebula really does look like a flying bird, but it’s a little too big to fit in the field of view of my telescope – so I focused instead on its “head” where most of the…
Part of our Local Group of galaxies, the Triangulum Galaxy (M33) is about 3 million light years away and the most distant object visible to the naked eye under dark skies.
Our new house has plenty of land, reasonably dark skies, and a reasonable homeowner’s association… so of course I had to try building an observatory! It may sound crazy, but it does offer a lot of advantages: I no longer have to set up my telescope, wait for dark, polar align it, and run a…
As Halloween draws closer, this seems like an appropriate object to image: the “Witch’s Broom” nebula! Although to be honest, that bright star (Cygnus 56) looks more like an eye on some sort of fantastical, cosmic creature to me. In reality, it’s part of the larger Veil Nebula, which is a huge supernova remnant 1,400…
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…
