  • Milky Way over the Hoodoos

    Milky Way over the Hoodoos

    This is Bryce Canyon in southern Utah, with the Milky Way glowing over the horizon. The astonishing rock formations, the Hoodoos, which make Bryce Canyon so famous, provide an interesting foreground for the heart of our Galaxy. The millennia of time required to create and erode the Hoodoos makes a very appropriate metaphysical foil to the millennia needed for the light of our own Galaxy to reach us.

  • Milky Way Over The Grand Canyon

    Milky Way Over The Grand Canyon

    Milky Way over the Grand Canyon. While taking this shot, there was a very sudden and loud crunching and ripping sound in the dark. The long exposure gives the impression of it being fairly light, but was actually pitch black and I was standing right against the Canyon rim... The noise was very close and nearly made me jump into the void! A few seconds later, the same noise happened again.... At this point I lost all interest in preserving my night vision and turned on my flashlight. A large Elk was standing just a few feet from me. The noise was the Elk browsing on the small tufts of grass emerging from rock crevices. I never heard a sound from its approach. But it completely ignored me (and my flashlight) and eventually melted away into the darkness.

  • Monument Valley

    Monument Valley

    As night follows day, this is Monument Valley, but with the Milky Way behind the Mittens. There's a funny story associated with this image.... aficionados of the night sky, familiar with Monument Valley, may notice the Milky Way galactic center is about 1/3 of the way too far to the left than it should be. Most high definition astrophotography shots are taken using a precision tracking mount, and this image is no exception. This image required two hours of accumulated exposure time, and so the foreground is always completely blurred if the stars are to be trail free. The procedure, always, is to add the sky image back into a static foreground shot. So... you'd think an astrophotographer would know which direction the sky rotates! Using the first frame of the image stack as a reference, I mistakenly applied a Right Ascension (RA) correction estimate for looking northwards..... but the image here was taken looking south east..... Duh! So I placed the sky in the image using the opposite rotation and translation. So, like I said, you'd think I would know which way the sky rotates! But the final image is very pleasing so I have left things as they are with my error. Please enjoy my artistic license! I am indebted to my good friend, and much better astrophotographer than me, Dr. Robert Fugate, for spotting my foolishness!

  • Celestial Schoolhouse

    Celestial Schoolhouse

    Celestial Schoolhouse. This is a 3 hour star trails exposure of the old School House at Lake Hope, near Zaleski, in southeastern Ohio. The two very bright trails on the right hand side are the rise of Venus and the crescent Moon.

  • Milky Way over Zion Valley

    Milky Way over Zion Valley

    This is our Milky Way galaxy rising over Zion Valley in the Zion National Park in Utah. In the summer time the core of the Milky Way is visible above the horizon and long exposure photography reveals a multitude of stars, dust lanes and nebulae in extraordinary detail. Zion Valley is so dark and free of light pollution that the Milky Way actually casts a shadow on moonless nights. Sadly, growing global light pollution, made even worse by newer LED lights, means that few people will ever see this sight. Just a century ago this was visible from anywhere in the world.

  • Triangulum Galaxy, M33

    Triangulum Galaxy, M33

    The Triangulum galaxy, also known as M33, was officially discovered by Charles Messier in August 1764, although it is likely that the Italian astronomer Giovanni Battista Hodierna also observed the same galaxy in 1654. It’s a beautiful example of a spiral galaxy, smaller than our own galaxy, with an estimated 40 billion stars. The Triangulum galaxy is just over 3 million light years from us and has a diameter of about 60,000 light years. The light that formed this image left the galaxy shortly after human beings began to walk on two legs and has only just arrived. It’s a shocking reminder of how BIG the universe really is, and how insignificant we are on the cosmic scale.

  • Orion Nebula

    Orion Nebula

    The place where stars are born. This is the Orion Nebula, located just below Orion's Belt in the constellation of Orion, and is a vast nursery for newborn stars. Small to the naked eye, this is one occasion where I used a telescope to capture the image. Small as it appears, the Orion Nebula is actually around 24 light years across and 1350 light years from earth.

  • North American Nebula

    North American Nebula

    The North American Nebula. At this time of year it is almost directly overhead around 3:00 am in the morning in the USA. It is large enough to be seen clearly with binoculars. You can easily see the dark shape of the "Gulf of Mexico" in the Nebula. The bright blue-white star is Deneb and it is the brightest star in the constellation Cygnus. Although Deneb is around 1425 light years from earth, it is a fiercely powerful star with a luminosity more than 50,000 times that of our own sun. But it is burning so fast that it is unlikely to outlive our own sun and is expected to become a supernova sometime in the next few million years. Interestingly, since our Earth wobbles gradually over time (precesses) Polaris, our pole star, won't always be our pole star. Thousands of years ago Deneb appeared close to where Polaris appears to be relative to Earth. Deneb will once again be our pole star in around 10,000 years time. But for me, the most fascinating aspect of this image is the density of stars... take a look on full screen and zoom in a little. There are thousands and thousands of visible stars. The fascinating bit is that if you count all the Stars visible in the heavens, there are more galaxies than this number, each containing a similar number of stars.... Aren't we small and insignificant on this scale? Life out there has to exist somewhere.

    Sci-Fi

    The picture is a composite of two images. The foreground is of the very beautiful and moving Armenian Genocide Memorial in Yerevan, Armenia. The foreground was taken facing into the sun with the sun just obscured by the tip of the memorial. The background is the Andromeda Galaxy, captured from the Zaleski State Forest in Ohio using a celestial tracking mount.

  • Sanibel Island Stars

    Sanibel Island Stars

    So many stars... This is a midnight shot taken on Sanibel Island, just off the coast from Fort Myers in Florida. The summer time humidity was extremely high, hence the haze towards the horizon. But, oh my, the sky was filled with stars.

  • Moon Composite

    Moon Composite

    This is a composite shot in honor of the “super moons” that have hit the headlines in recent years. The foreground is regular astrophotgraphy shot of the Milky Way rising over a misty field in Zaleski State Forest in southeastern Ohio. The moon appears much larger than real life, taken with a powerful telephoto lens and superimposed against the Milky Way sky. I love the contrast between the celestial Moon and the soft misty landscape.

  • Corona Arch

    Corona Arch

    Arches National Park at Moab in Utah is a breathtaking area of natural beauty. Perhaps less well known are the arches outside the National Park. This beauty lies due south from the famed Arches National park, and a little west from the town of Moab. It’s quite a hike to get to this arch, involving a couple of miles scrambling up steep cliff-side trails, a steel ladder climb, and clinging to a rope walkway. Getting there (and back) in the dark is quite an experience! But the trek is worth it when you’re rewarded with this gift of nature.

  • Goblin Valley

    Goblin Valley

    This is Goblin Valley in deepest Utah, miles from anywhere. This is the darkest sky I have experienced - "Bortle 1", the darkest possible. "Dark" is misleading here as it just means there was no light pollution at all so all the stars become visible. There were so many stars that the Milky Way casts a shadow and it became all but impossible to find the constellations. An amazing place.

  • Devil's Garden

    Devil's Garden

    This is the "Devil's Garden" at the northern end of the Arches National Park in Utah. This is the view north, so the Milky Way is out of the shot. But wow! So many stars! The sky is dark enough to see air glow close to the horizon (orange color), not to be confused with the light pollution from Moab on the lower right.

  • Rosette Nebula

    Rosette Nebula

    This is the beautiful Rosette Nebula, which appears in the southern skies of the Northern hemisphere in the winter months. It's a massive remnant of an ancient super nova, when an old star ran out of fuel and erupted into the heavens, spewing unimaginable amounts of energy and matter into the surrounding universe. The image shown here took 5 hours to accumulate, using multiple shots through a 530 mm focal length lens on a tracking mount. The night was COLD, dropping down to 5 F; I was glad once I had the shot!

  • Andromeda Galaxy

    Andromeda Galaxy

    This is the Andromeda Galaxy captured with narrowband hydrogen alpha light overlaid onto a regular RGB image. All of the tiny red "blobs" are actually giant emission nebulae in the Andromeda galaxy.

  • Heart Nebula

    Heart Nebula

    This is the Heart Nebula, also known as IC1805, captured using three narrowband filters for Hydrogen, Sulphur and Oxygen emission. This image uses the so-called "Hubble Palette", in which a false color image is constructed using a monochrome camera plus individual narrow bandwidth filters to create an RGB image. Here, the Hubble palette is "SHO" where red = sulphur, green = hydrogen, blue = oxygen.
