Triangulum Galaxy
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.

The Dumbbell Nebula (M27) is what’s called a planetary nebula – but it has nothing to do with a planet. This shell of gas was blown out by a dying star; once it started to run out of Hydrogen to burn, it expanded and blew out the gases you see here. The star then collapsed…
M13, the great globular cluster in Hercules. You can see some of its interesting neighbors, including the galaxy NGC 6207 in the lower-left. While M13 itself is 25,000 light-years away just above our galactic plane, NGC 6207 is 37 million light-years distant. About halfway between the two, the galaxy IC 4617 is also visible –…
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 the Christmas Tree Cluster (turn the picture upside down and you might see it!) But the real focus here is the Cone Nebula at the bottom of the image, and the Fox Fur Nebula in the upper-right. Lots of red Hydrogen gas here being ionized by the young stars it formed. Also visible…
It’s a good thing galaxies don’t have feelings; they’re just collections of billions of stars. Because NGC 2903 would need therapy. It has no cute nickname like other galaxies; it’s just NGC 2903. And it has no galactic neighbors; most galaxies are gravitationally bound to other galaxies in their local group or cluster, but NGC…
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…
