Going Deep with the Horsehead and Flame
The Horsehead and Flame nebulas, although popular, are really difficult to image together. The clouds of Hydrogen look best using narrowband filters, but the blue reflection nebula below the Horsehead only appears in wideband, color filters. Further complicating matters is the bright star Alnitak, one of the stars that makes up Orion’s belt. In narrowband,…

Thor’s Helmet
An interesting emission nebula 30 light years across. Imaged with narrowband filters.

Off to See the Wizard (again)
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…

The “Bubble Nebula”
Here’s my latest image of the “Bubble Nebula”, one of my favorite objects in our galaxy. That blue “bubble” is a shell of gas pushed out by the stellar wind of the bright star just right of its center. It’s a big star, 10-20 times larger than our sun. Its radiation is also illuminating and…

Playing with Pac-Man
This is NGC281, or the “Pac-Man” nebula. I think it’s one of those objects that might look a little like its name if you’re viewing it through a big telescope in a dark sky, but takes on a totally different character in long-exposure, narrowband images such as this. This is a total of 13 hours…

Revisiting “Thor’s Helmet”
Domey McDomeFace’s days are numbered, I’m afraid! Our property is up for sale, and hopefully its new owner will continue to use it to produce amazing images of their own. Meanwhile, I’m taking advantage of every clear night I can, while we’re still here. Here’s one of my favorite objects: “Thor’s Helmet” or NGC2359. Like…
