Here’s IC417, commonly known as the “Spider Nebula.” Just outside of the frame is a smaller one called the “Fly Nebula,” but my field of view isn’t quite big enough to capture them together! It’s about 10,000 light-years away, in the constellation Auriga. Imaged over 15 hours; narrowband nebula blended with RGB stars.
Last night I revisited M63, the Sunflower Galaxy. More formally M63, the Sunflower Galaxy is about 25 million light-years away. It’s about the same size as our Milky Way, but is classified as a “flocculent spiral” galaxy due to its poorly defined spiral arms. The more distant edge-on spiral galaxy on the right doesn’t show…
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…
NGC253 is most commonly known as the “Sculptor Galaxy,” because it’s found within the constellation Sculptor. You probably haven’t heard of Sculptor – that’s because it is considered a Southern-hemisphere constellation, and it’s only visible in the US from Southern states such as Florida. It’s also known as the “Silver Coin Galaxy.” It’s part of…
Now that our new backyard observatory is up and running, and we’re under darker skies than in our previous home, I’m revisiting some galaxies I’ve imaged before to see how things compare. Galaxies are tough… any amount of light pollution or moonlight really limits your ability to capture faint, wispy details. But the less light…
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…
