Globular Cluster M3

As we enter summer and the Earth starts pointing us back into the plane of the Milky Way and its many nebulas, we’re nearing the end of globular cluster season. M5 seems a fitting one to end on this year; there’s nothing terribly remarkable about it, other than I think it’s pretty. It’s located about…

This one’s also known as the “Silver Sliver” Galaxy, or more formally NGC 891. It’s about 30 million light-years away, well beyond our own local group. It’s thought to be quite similar to our own Milky Way! What I really geek out on, though, is the wider views here – there are so many other…

There’s a reason I’ve been quiet lately – we sold our house and are in the process of moving to Los Angeles! Also, Florida’s weather hasn’t been terribly cooperative either. The sad news is that we had to leave the observatory behind, and I donated its equipment to the Central Florida Astronomical Society, as LA…

If you point your telescope outside of the Milky Way, you’re almost guaranteed to pick up very distant galaxies, because there are just so many of them out there. This patch of sky inside Cancer is a cluster of galaxies called Abell 671. If you click the image and look at it full size, you’ll…

Our new house has plenty of land, reasonably dark skies, and a reasonable homeowner’s association… so of course I had to try building an observatory! It may sound crazy, but it does offer a lot of advantages: I no longer have to set up my telescope, wait for dark, polar align it, and run a…

Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…
