This solar cycle has been quite a bit more active than forecast. It motivated me to up my game a little bit with solar imaging; this is my first image with a “double stack” setup that results in narrower filtering on the Hydrogen-alpha emissions from the sun. Lots and lots of prominences, filaments, and sunspots going on there!
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…
Johan Bode discovered both Bode’s Galaxy (M81, on the left) and the Cigar Galaxy (M82, on the right.) Look closely and you’ll see many other, more distant galaxies in the background as well.
The Cocoon Nebula in Cygnus is a compact cloud of Hydrogen, lit up by the bright star in its center. Dust lanes can also be seen across it, obscuring the ionized Hydrogen gas behind them. This object is best imaged during the heart of Summer, which means really challenging conditions here in Florida. High humidity,…
M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.
At the center of this image is the distant galaxy NGC210, 65 million light-years away within the constellation Cetus. It’s mind-blowing that we can capture an image of something so distant from our backyards, given the right technology. It’s also mind-blowing that we’re looking at light that has been traveling for 65 million years, giving…
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,…
