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.
There are a lot of stars in this picture; the gases of the Wizard Nebula (formally SH2-142) are the birthplace of those stars, and more are being created even now. It’s located about 7,200 light-years away, and is extremely dim – it took over 9 hours of exposure time to capture this image. Your ability…
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
This nebula goes by the unassuming name of SH2-9. It’s part of a larger complex of clouds known as the Rho Ophiuchi complex, but you don’t often see people focusing on this part of it. It’s a challenge to image from my location, as it’s very low in the sky in a light-polluted direction. There…
Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…
Every year I try and do a better job of capturing and processing the Bubble Nebula in Cassiopeia. Here’s this year’s attempt. The Bubble Nebula is one of my favorite objects. Not only is it interesting scientifically (the bubble is the stellar wind of a hot O-type star blowing away the surrounding gases,) it’s also…
There’s a comet in the sky! They don’t appear this bright very often, so don’t miss what could be a once-in-a-lifetime chance to see a comet with your own eyes. It’s tough to spot here in suburbia with your eyes, but it’s easy to see with binoculars. Its official name is C/2020 F3 NEOWISE. Just…
