Revisiting the Northern Pinwheel Galaxy (M101)

Revisiting the Northern Pinwheel Galaxy (M101)

Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…

NGC2336

Looking back to the age of dinosaurs (NGC2336 and IC467)

Spent a couple of nights imaging these distant galaxies; the spiral in the upper-left is NGC2336, and the other is IC467. Galaxies this faint and distant generally don’t have catchy names! NGC2336 is 100 million light-years away. Think about that – you’re looking 100 million years in the past. The light we captured started its…

Spider Nebula

The Spider Nebula

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.

Cave Nebula

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…

The Elephant’s Trunk

The Elephant’s Trunk

Located about 2,400 light-years away in the constellation Cepheus, the “Elephant’s Trunk Nebula” has a distinct “Pillars of Creation” vibe when viewed as a long-exposure, narrowband image in the style of Hubble. Like the “Pillars of Creation” (the Eagle Nebula,) the Elephant’s Trunk is also an area of star formation, containing some young, newly-formed stars….

Here’s our solar system in a few billion years.

Here’s our solar system in a few billion years.

This is M27, the “Dumbbell Nebula,” about 1600 light-years away. It’s what’s called a planetary nebula – not because it has anything to do with planets, but because early observers confused them for planets. In reality it’s far more interesting. This is what’s left over when a medium-sized star runs out of Hydrogen to fuse,…

A bunch of obscure galaxies in Virgo (NGC5364 and friends)

A bunch of obscure galaxies in Virgo (NGC5364 and friends)

There’s a big cluster of galaxies within Virgo; it’s just filthy with them. People usually image a different part of it, but I found another interesting area that’s often overlooked. The grand-design spiral at the bottom is NGC5364; it’s about 55 million light-years away. The annotated image identifies its buddies.

NGC 3344: Another obscure, isolated galaxy

NGC 3344: Another obscure, isolated galaxy

Here’s another galaxy with no nearby neighbors, and no catchy nicknames either: NGC 3344. It’s about 22.5 million light-years away within the constellation Leo Minor. Although it doesn’t get the love it deserves, it’s a glorious face-on barred spiral galaxy that’s about half the size of our own Milky Way. Explore the space around it,…

NGC2903 feels lonely.

NGC2903 feels lonely.

It’s a good thing galaxies don’t have feelings; they’re just collections of billions of stars. Because NGC 2903 would need therapy. It has no cute nickname like other galaxies; it’s just NGC 2903. And it has no galactic neighbors; most galaxies are gravitationally bound to other galaxies in their local group or cluster, but NGC…

Going deep on the Cone and Fox Fur Nebulas

Going deep on the Cone and Fox Fur Nebulas

About 2,700 light-years away within the constellation Monoceros lies the Cone and Fox Fur Nebulas, containing the “Christmas Tree Cluster” of stars as well. I’ve imaged this many times before, but have never been happy with the results. By combining data from last year with more data collected this year however, I finally got enough…

The galaxy NGC2841, 46 million light-years away.

The galaxy NGC2841, 46 million light-years away.

This is a somewhat obscure target; at 46 million light-years distant, it’s hard to capture much detail on it from Earth. But that’s what makes it interesting and challenging! Located within the constellation Ursa Major, this is a flocculent spiral galaxy notable for its massive central core. Look around in the background, and you’ll find…

Wizard Nebula

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 Iris Nebula

The Iris Nebula

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…

The Cocoon Nebula

The Cocoon Nebula

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,…
