Kind of an interesting framing on this one – it looks like it’s reaching out! This is narrowband emissions, in the Hubble Sulphur/Hydrogen/Oxygen palette. Some say there’s no Oxygen emission in this one, but with enough determination I pulled it out – that’s what results in the purples and blues you see here.
This one’s also known as the “Silver Sliver” Galaxy, or more formally NGC 891. It’s about 30 million light-years away, well beyond our own local group. It’s thought to be quite similar to our own Milky Way! What I really geek out on, though, is the wider views here – there are so many other…
Here’s 20 hours of exposure time on the Pleiades in Taurus… a lot of people call this the “little dipper” since it does look like a tiny one to the eye, but the little dipper is a larger constellation. Although it’s known as the “seven sisters,” in fact it’s a cluster of a thousand or…
Both on Earth, and in space! While we prepare for a year or two in California, I trained Scopey von Scopington on the California Nebula for a few nights. Pretty obvious how it got its name! This is a two-panel mosaic, consisting of narrowband SHO data for the nebula and broadband RGB for the stars….
My first image from Starfront Observatories in Central Texas! They’ve been fantastic to work with so far, and I’m really stoked to be able to image remotely from anywhere, under clear, dark skies. While collecting data on M33, the “Triangulum Galaxy”, I was still fine-tuning everything and figuring things out – so there are things…
There’s a reason I’ve been quiet lately – we sold our house and are in the process of moving to Los Angeles! Also, Florida’s weather hasn’t been terribly cooperative either. The sad news is that we had to leave the observatory behind, and I donated its equipment to the Central Florida Astronomical Society, as LA…
Busted out the solar telescope, now that fall has finally come to central Florida and the weather’s nice again! We’re still in the midst of a solar maximum, and today’s flares did not disappoint. We kept the ‘scope out all day, and observed a smaller flare seen across from the big ones turn into a…
The galaxies NGC4567 and NGC4568 are colliding 60 million light-years away. This is really pushing the resolution limits here; we had good “seeing” last night meaning not a lot of turbulence to smear out the light reaching my telescope, and I carefully collimated and calibrated things prior to imaging last night. About as good as…
Messier 88, within the constellation Coma Berenices, is part of the nearby Virgo cluster of galaxies. And by “nearby”, I mean 50-60 million light years away! The light we’re seeing from this galaxy originated from the time of the dinosaurs. Telescopes are really time machines. There are many other galaxies surrounding M88, both smaller and…
This edge-on spiral is around 40 million light-years away within the constellation Coma Berenices. Lots of satellite and background galaxies to explore around it! Zoom in, and travel back in time – hundreds of millions of years.
Within the constellation Corvus, two galaxies are close to merging together into one… leaving two tails behind from the original galaxies. About 45 million light-years away. Our own galaxy may suffer a similar fate, should it collide with the Andromeda Galaxy in the distant future.
A nebula that looks like its name! Formally SH-308, this bubble of gas 60 light-years across is blown out by a hot Wolf-Rayet star at its center. It’s about 4500 light-years away in the constellation Canis Majoris. It’s quite dim, but if you could see it with bionic vision or something, it would be larger…
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…
This is my first attempt at a mosaic… basically stitching together three views of an object that’s normally too large in the sky to fit within the field of view of my telescope. It came out alright! We’ve had a great run of clear nights the past few weeks in Florida, and I’ve invested just…
The Bubble Nebula still has a soft spot in my heart… it’s what really got me going with astro-imaging years ago. It’s just such a fascinating, gorgeous object and it really inspired me the first time I saw it. Here’s my deepest exposure of it yet: over 20 hours of exposure time, in the “Hubble…
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…
The Pelican Nebula frankly isn’t a very attractive object as a whole, but if you crop it down to its heart, there’s a lot of interesting stuff going on. Look for little puffs in the image, or areas with spikes coming out of them. Those are Herbig-Haro objects – stars that are still in the…
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…
That massive sunspot group rivals the size of the one that triggered the Carrington Event in 1859. So far it has kicked off some large coronal mass ejections heading our way, but fortunately nothing on that scale. Let’s hope we just get some pretty auroras from this, and nothing more damaging!
Combining 25 hours of data shot over two years, here’s M64. It’s an odd one, with counter-rotating disks that seem to have funneled all that dust in the center there. They think it’s the result of a merger of two galaxies that were spinning in opposite directions. Located about 17 million light-years away, in the…
I wasn’t able to travel to the path of totality, but here from Florida we still had a partial eclipse. Here’s my shot at its peak, viewed through a special solar telescope using a Hydrogen-Alpha filter to bring out all the roiling detail of the sun’s surface. Check out those prominences around the edge!
It’s been awhile since I imaged the “Leo Trio” (aka Leo Triplet) of galaxies: M65, M66, and NGC 3628. I wanted to see if my latest equipment, software, and somewhat darker skies made a difference. I’d say so… this is a total of 25 hours of exposure time, including some Hydrogen-alpha filter data to pull…
Located 63 million light-years away in the constellation Coma Berenices, M91 is part of the Virgo cluster of galaxies – and if you zoom in and explore this image, you’ll find many other galaxies surrounding it, and also far in the distance beyond it.
Last weekend, I hosted an astrophotography workshop on lunar photography for our local astronomy club. Tonight the skies finally cleared, and I got to apply what was learned! Here’s our lunar neighbor, in hi-res glory.
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…
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.
The “California Nebula” (NGC1499) does actually kinda look like California, if you look at the whole thing. But the whole thing is too big in the sky to fit within the field of view of my telescope. So, here’s an interesting portion of it near one of its ends at least. From this angle, it…
A lot of things have to come together for a good image of the planets. The air needs to be as still as possible, the planet you’re imaging needs to be as directly overhead as possible, and the planet itself should be as close to the Earth as possible. And then, all your equipment has…
This image really blows my mind – this is the reflection nebula NGC1333 in Perseus. The blue part is reflected gas and dust from the star that’s lighting up – that’s nothing too unusual. But check out the little red blobs above it. Many of those are “Herbig-Haro” objects, formed by jets spewing out from…
This was intended to just be an image of the galaxy M77 in Cetus, but quite a few other galactic photobombers showed up! The annotated image below guides you to the brighter galaxies in this image, but click on it to expand it, and you’ll find many other ones as well that are incomprehensibly distant.
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…
This is IC342, located about 10 million light-years away. If it were anywhere else in the sky, it would be visible to the naked eye – but it lies behind the disk of our Milky Way galaxy, obscuring the view. This image is the result of 22 hours of total exposure time to try and…
Central Florida wasn’t on the path of the “ring of fire” annular eclipse, but we did get about 60% coverage during the peak of our partial solar eclipse today! I was live-streaming the view at the peak, but managed to capture a quick image for myself shortly afterwards. Lots of good flares and prominences, and…
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…
I just added a Lunt 40mm solar telescope to the arsenal here… figuring it out was challenging, but eventually I got it working! This ain’t bad for my very first solar image; still lots to learn though.
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….
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,…
I’ve imaged this one before, but I keep coming back to it because I just can’t believe its golden color is real. But even after applying all I’ve learned about color calibration – I can say pretty definitely that these are its true colors. It’s also benefited from advances in image processing software, making the…
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.
The galaxy M106 is an interesting one; it’s large and relatively bright – about the same size as Andromeda. And it’s in a busy part of the sky, within Canes Venatici, with lots of galactic neighbors. This image has been enhanced with Hydrogen emission data; that’s what the red dots and tendrils are. There’s one…
Sometimes called the “Cat’s Eye Galaxy,” this is M94 – about 16 million light years away in the constellation Canes Venatici. You can barely see its faint outer ring surrounding it here, as well as several very distant background galaxies. It’s notable for challenging our understanding of the universe – it appears to have very…
This pair of galaxies gets its name from their shapes. Both are viewed edge-on, and from this perspective we can see how a past interaction between the two warped them both. About 6 hours of exposure time from the backyard observatory.
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,…
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…
I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…
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…
This comet will reach its brightest point a couple of weeks from now, but the skies were clear this morning so I figured I should go for it while I can! The tail’s not as pronounced as I hoped, and processing is a bit sloppy in a couple of spots. But hey, it’s a comet….
Had a couple of clear nights recently, and trained the ‘scope at the Rosette Nebula again. By combining this year’s data with last year’s, I created an image with a total 27 hours of exposure time! The Rosette Nebula is about 5,000 light-years away within the constellation Monoceros, and is the birthplace of the cluster…
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…
Formally NGC1570, the “Northern Trifid” is a combination of an emission nebula (the red parts, which is ionized Hydrogen emitting its own light) and a reflection nebula (the blue parts, which is starlight reflecting off dust.) You can also see hints of the dust surrounding this area, which is difficult to capture under the light-polluted…
