The Moon

I shot this object in a few different ways. Here’s how it looks in pure “LRGB” light – how it would appear to the eye in its natural wavelengths, if your eyes could detect color on something so dim! And here’s a narrowband take on this same object. Notice that the structure of its core…

A nebula that looks like its name! Formally SH-308, this bubble of gas 60 light-years across is blown out by a hot Wolf-Rayet star at its center. It’s about 4500 light-years away in the constellation Canis Majoris. It’s quite dim, but if you could see it with bionic vision or something, it would be larger…

One of the largest and oldest (13 billion years) globular cluster of stars near our galaxy – there are hundreds of thousands of stars in there. There are some interesting theories that globular clusters such as this are what remains of smaller galaxies that our Milky Way has consumed – this is just what’s left…

Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it…

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…

Another revisit of an old target, with better gear and better conditions. This is the Pelican Nebula in the constellation Cygnus. Shot in narrowband over one night, and presented in the “Hubble palette”. Two takes – one wider field, and one close-up with the stars removed. In both cases the image is rotated and mirrored…
