This notoriously dim supernova remnant in Cassiopeia is formally known as CTB1. It took 46 hours of exposure time – most of that narrowband through Hydrogen and Oxygen filters – to pull out this detail. I’m pretty proud of this one; it holds its own amongst the better captures of this object. As usual, I…

This is a very faint planetary nebula about 1800 light-years away in the constellation Lepus. The white dwarf at its center is what’s left of a ten billion year old star that blew itself out about 20,000 years ago. Over 33 hours of HOO exposure on this. I’ve seen prettier pictures of it, but I…

Somewhere between 30 and 50 million light-years away, within the constellation Coma Berenices, lies NGC4565 – commonly known as the “Needle Galaxy”. It’s a spiral galaxy, but viewed edge-on – so we see its central bulge and the edge of the galaxy’s disc extending from it. Clouds of dust within the galaxy obscure the middle…

This is IC342, located about 10 million light-years away. If it were anywhere else in the sky, it would be visible to the naked eye – but it lies behind the disk of our Milky Way galaxy, obscuring the view. This image is the result of 22 hours of total exposure time to try and…

This gorgeous nebula, formally known as NGC281 in the constellation Cassiopeia, goes by the informal name of “The Pac-Man Nebula.” I don’t see a Pac-Man. I think it’s a case where if you look at it through a telescope with your eyes, you only see the brightest parts – and then, maybe it looks a…

This image really blows my mind – this is the reflection nebula NGC1333 in Perseus. The blue part is reflected gas and dust from the star that’s lighting up – that’s nothing too unusual. But check out the little red blobs above it. Many of those are “Herbig-Haro” objects, formed by jets spewing out from…
