The “Leo Trio” of galaxies

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…

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 –…

Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…

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…

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…

Every year I image the “Whirlpool Galaxy” (really a pair of galaxies interacting with each other,) and every year it gets a little bit better. This year it was shot from our new observatory, on a newly-tuned mount and with some more image processing experience under my belt. It’s also under slightly darker skies, which…
