Revisiting M13 in Hercules
M13 is one of the most photogenic and popular globular clusters, and it’s pretty easy to see with nothing more than a pair of binoculars if you know where to look! But it’s even prettier with a long exposure – this is about 3 hours of exposure time. Blow it up to full size, and…

The Ghost of Cassiopeia
It doesn’t take much imagination to see a ghost leaving a trail of ectoplasm in this cloud of Hydrogen gas, lit up by the bright star Navi. To keep with a spooky and ethereal theme, I photographed this object in monochrome using only a Hydrogen-alpha filter.

The Iris Nebula
Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…

Goodness gracious, great balls of… oxygen?
Well, it was certainly born of fire. This is planetary nebula Abell 39, one of the largest spheres in the galaxy… it’s 2.6 light-years across! It really is that color blue. You’re seeing ionized Oxygen gas blown off by the dying star in its center. Look closely for the distant galaxies in the background, including…

Revisiting the Needle Galaxy
This edge-on spiral is around 40 million light-years away within the constellation Coma Berenices. Lots of satellite and background galaxies to explore around it! Zoom in, and travel back in time – hundreds of millions of years.

The Whirlpool Galaxy
The Whirlpool Galaxy (M51) appears to be sucking the life out of its companion, NGC 5195. While these galaxies are interacting, they’re not actually connected right now – it just looks that way.
