M51, the Whirlpool Galaxy – Another year, another try
Every year I image the “Whirlpool Galaxy” (really a pair of galaxies interacting with each other,) and every year it gets a little bit better. This year it was shot from our new observatory, on a newly-tuned mount and with some more image processing experience under my belt. It’s also under slightly darker skies, which…
Mars Fever
The amateur astronomy community is pretty excited at Mars lately – it’s nearing its closest approach to Earth right now, and this one’s even closer than usual. That means some of the best viewing and imaging opportunities for the Red Planet you’ll ever get. When the skies clear and the atmosphere is still, it’s an…
Goodness gracious, great balls of… oxygen?
Well, it was certainly born of fire. This is planetary nebula Abell 39, one of the largest spheres in the galaxy… it’s 2.6 light-years across! It really is that color blue. You’re seeing ionized Oxygen gas blown off by the dying star in its center. Look closely for the distant galaxies in the background, including…
The Pelican Nebula
Granted this is only a portion of it, but for the life of me I don’t see a pelican in this thing. But, it’s still pretty. I processed this object two ways: using the “Hubble palette” that maps red, green, and blue to Sulfur, Hydrogen, and Oxygen emissions (that results in the pretty blue one)…
Revisiting the Veil Nebula
It’s been a long time since I targeted the Veil Nebula – it’s so bright that it’s hard to screw up, so what was the point? But it’s definitely looking a little better using newer equipment, software, and darker skies – plus my processing skills are a little better. Looking back at my original images…
The Cave Nebula
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…
