Halo Around the Moon


Halo Around the Solstice Moon

On the night before the solstice Full Moon, the sky added a coloured halo around the Moon.

On June 19 I was at Waterton Lakes National Park, Alberta to teach a workshop on night photography, as one of the programs of the Park’s annual Wildflower Festival. The night proved hazy, but that added the attraction of an ice crystal halo around the Moon.

The lead image above is from Driftwood Beach, looking south across Middle Waterton Lake. Note Mars shining above the mountains at right.

Earlier in the night, at Red Rock Canyon, we watched the Moon rise in the twilight, then climb up the side of Mt. Blakiston. Here (below) it shines above the summit, surrounded by its hazy halo.

This is a high-dynamic range stack of 6 exposures, to avoid the area around the Moon from blowing out too much while recorded detail in the dark foreground. All with the 20mm lens and Nikon D750.

The workshop participants made the best of the night, shooting the moonlit scene down the canyon, toward the north and Cassiopeia.

And as here, shooting from the canyon footbridge, toward the very photogenic Anderson Peak, with Jupiter just above the peak.

In keeping with the wildflower theme, I shot wild roses, Alberta’s provincial flower, in the moonlight, with Anderson Peak and stars in the distance.

This is a single exposure at f/8 for 20 seconds at ISO 3200 with the 20mm lens and Nikon D750.

While we might like dark skies when going to places like Waterton, there are many magical options for photography when the Moon is shining.

Mars in the Moonlight


Mars in the Badlands

Mars is approaching! It now shines brightly in the midnight sky as a red star in Scorpius.

You can’t miss Mars now. It is shining brighter than it has since 2005, and is about to come as close to Earth as it has in 11 years as well.

Mars is now approaching opposition, when the Earth comes closest to Mars, and the Sun, Earth and Mars lie along the same line. Opposition date is May 22. That’s when Mars shines at its brightest, at magnitude -2.1, about as bright as Jupiter. Only Venus can be a brighter planet and it’s not in our sky right now.

A week later, on May 30, Mars comes closest to Earth, at a distance of 75 million kilometres. That’s when the disk of Mars looks largest in a telescope. And you will need a telescope at high power (150x to 250x) to make out the dark markings, north polar cap, and bright white clouds on Mars. 

Mars in the Moonlight (May 13, 2016)
Mars above Antares, with Saturn to the left, low in the south on May 13, 2016, in the moonlight of a waxing quarter Moon, from home in Alberta. This was one week before opposition and two weeks before closest approach, so Mars is particularly bright and red. However, from my latitude of 50° N Mars appears low in the south. This is a single 15-second exposure, untracked, at f/2.5 with the 35mm lens and Canon 6D at ISO 2000.

In these views, I show Mars shining as a bright reddish star low in my western Canadian sky. I shot the lead image from Dinosaur Provincial Park on May 16. The image just above was from my backyard the night before.

This week, Mars is passing between Beta and Delta Scorpii, two bright stars in the head of Scorpius, as the red planet retrogrades westward against the background stars.

Saturn shines to the east (left) of Mars now, with both planets shining above the red giant star Antares in Scorpius. In these photos they form a neat triangle.

Even without a telescope to magnify the view, it’ll be rewarding to watch Mars with the unaided eye or binoculars as it treks west out of Scorpius into Libra this spring and summer. It stops retrograding on June 30, then starts looping back into Scorpius, for a rendezvous with Antares and Saturn in late August.

This little compilation of time-lapse movies shows Mars, Saturn, and the rest of the sky, rising into the southeast and across the south on two nights this past week.

Be sure to explore Mars this month and next, whether by eye or by telescope. It’s the best we’ve seen it in a decade.

It’s next close approach in 2018 will be even better, though Mars will appear even lower in our northern sky.

Orion Star Trails in the Moonlight


Orion Rising in the Moonlight

Orion ascends into the sky on a clear autumn night, with its stars drawing trails behind it as it rises.

Only on November nights is it possible to capture Orion rising in the evening sky. Here, I used the light of the waxing gibbous Moon to illuminate the landscape … and the sky, creating the deep blue tint.

The lead image above is an example of a star trail, a long exposure that uses Earth’s rotation to turn the stars into streaks across the sky. In the old days of film you would create such an exposure by opening the shutter for an hour or more and hoping for the best.

Today, with digital cameras, the usual method is to shoot lots of short exposures, perhaps no more than 20 to 40 seconds each in rapid succession. You then stack them later in Photoshop or other specialized software to create the digital equivalent of a single long exposure.

The image above is a stack of 350 images taken over 2.5 hours.

With a folder of such images, you can either stack them to create a single image, such as above, or string them together in time to create a time-lapse of the stars moving across the sky. The short video below shows the result. Enlarge the screen and click HD for the best quality.

 

For the still image and time-lapse, I used the Advanced Stacker Plus actions from StarCircleAcademy to do the stacking in Photoshop and create the tapering star trail effect. A separate exposure after the main trail set added the point-like stars at the end of the trails.


 

My tutorial on Vimeo provides all the details on how to shoot, then stack, such a star trail image…


 

… While this video illustrates how to capture and process nightscapes shot under the light of the Moon.

 

Enjoy the videos! And happy trails!

Dawn Dance of Planets Concludes


The planet trio of Venus (brightest), Jupiter (above Venus) and Mars (dim and red to the left of Venus), all in Leo in the morning sky on November 1, 2015, with the waning gibbous Moon illuminating the landscape and sky. Even in the moonlight, the Zodiacal Light seems to be faintly visible along the ecliptic defined by the line of planets.  This is a stack of 6 x 30-second exposures at f/5.6 and ISO 2500 for more depth of the field for the ground, plus a 13-second exposure at f/2.5 and ISO 800 to minimize star trailing. The ground exposures were mean combined in a stack to smooth noise. Diffraction spikes added with Astronomy Tools Actions for Photoshop.

The gathering of planets at dawn is coming to an end as Venus meets Mars.

This was the view this morning from home in southern Alberta of the trio of planets in the moonlit morning sky.

Venus is the brightest, while dim red Mars shines just to the left of Venus. Jupiter is above the Venus & Mars pairing, with all the planets shining in Leo.

The planet trio of Venus (brightest), Jupiter (above Venus) and Mars (dim and red to the left of Venus), all in Leo in the morning sky on November 1, 2015, with the waning gibbous Moon illuminating the landscape and sky. The stars of Leo, including Regulus, shine above the planets. This is a stack of 4 x 30-second exposures at f/5.6 and ISO 2000 for more depth of the field for the ground, plus a 10-second exposure at f/2.8 and ISO 2000 to minimize star trailing. The ground exposures were mean combined in a stack to smooth noise. Diffraction spikes added with Astronomy Tools Actions for Photoshop.

Mars and Venus will appear closest to each other on November 2 and 3. Then the group breaks apart as Venus descends but Mars and Jupiter climb higher.

But as they do so they are joined by the waning Moon, by then a thin crescent, on November 6, when the Moon shines near Jupiter, and November 7, when it joins Venus for a stunning dawn sky scene.

After that the morning planet dance comes to an end. But in two months, in early January, Venus will meet up with Saturn for a very close conjunction in the winter dawn sky on January 9.

The Lunar Eclipse, to True Scale


This is a multiple-exposure composite of the total lunar eclipse of Sunday, September 27, 2015, as shot from Writing-on-Stone Provincial Park, Alberta, Canada. From this location the Moon rose in the east at lower left already in partial eclipse. As it rose it moved into Earth’s shadow and became more red and the sky darkened from twilight to night, bringing out the stars. Then, as the Moon continued to rise higher it emerged from the shadow, at upper right, and returned to being a brilliant Moon again, here overexposed and now illuminating the landscape with moonlight. The disks of the Moon become overexposed here as the sky darkened because I was setting exposures to show the sky and landscape well, not just the Moon itself. That’s because I shot the frames used to assemble this multiple-exposure still image primarily for use as a time-lapse movie where I wanted the entire scene well exposed in each frame. Indeed, for this still image composite of the eclipse from beginning to end, I selected just 40 frames taken at 5-minute intervals, out of 530 I shot in total, taken at 15- to 30-second intervals for the full time-lapse sequence. All were taken with a fixed camera, a Canon 6D, with a 35mm lens, to nicely frame the entire path of the Moon, from moonrise at left, until it left the frame at top right, as the partial eclipse was ending. The ground comes from a blend of 3 frames taken at the beginning, middle and end of the sequence, so is partly lit by twilight, moonlight and starlight. Lights at lower left are from the Park’s campground. The sky comes from a blend of 2 exposures: one from the middle of the eclipse when the sky was darkest and one from the end of the eclipse when the sky was now deep blue. The stars come from the mid-eclipse frame, a 30-second exposure. PLEASE NOTE: The size of the Moon and its path across the sky are accurate here, because all the images for this composite were taken with the same lens using a camera that did not m

My multiple-exposure composite shows the complete September 27, 2015 total lunar eclipse to true scale, with the Moon accurately depicted in size and position in the sky.

From my location at Writing-on-Stone Provincial Park in southern Alberta, Canada, the Moon rose in the east at lower left already in partial eclipse.

As it rose it moved into Earth’s shadow and became more red, while the sky darkened from twilight to night, bringing out the stars.

Then, as the Moon continued to rise higher it emerged from Earth’s shadow, at upper right, and returned to a brilliant Full Moon again, here overexposed and now illuminating the landscape with moonlight.


TECHNICAL

The disks of the Moon become overexposed in my composite as the sky darkened because I was setting exposures to show the sky and landscape well, not just the Moon itself. That’s because I shot these frames – and many more! – primarily for use as a time-lapse movie where I wanted the entire scene well exposed in each frame.

Indeed, for this still-image composite of the eclipse from beginning to end, I used just 40 frames taken at 5-minute intervals, selected from 530 I shot, taken at 15- to 30-second intervals for the full time-lapse sequence.

All were taken with a fixed camera, a Canon 6D, with a 35mm lens, to nicely frame the entire path of the Moon, from moonrise at lower left, until it exited the frame at top right, as the partial eclipse was ending.

In the interest of full disclosure, the ground comes from a blend of three frames taken at the beginning, middle, and end of the sequence, and so is partly lit by twilight and moonlight, to reveal the ground detail better than in the single starlit frame from mid-eclipse. Lights at lower left are from the Park’s campground.

The background sky comes from a blend of two exposures: one from the middle of the eclipse when the sky was darkest, and one from the end of the eclipse when the sky was now lit deep blue. The stars come from the mid-eclipse frame, a 30-second exposure.


MY RANT FOR REALITY

So, yes, this is certainly a composite assembled in Photoshop – a contrast to the old days of film where one might attempt such an image just by exposing the same piece of film multiple times, usually with little success.

However … the difference between this image and most you’ve seen on the web of this and other eclipses, is that the size of the Moon and its path across the sky are accurate, because all the images for this composite were taken with the same lens using a camera that did not move during the 3-hour eclipse.

This is how big the Moon actually appeared in the sky in relation to the ground and how it moved across the sky during the eclipse, in what is essentially a straight line, not a giant curving arc as in many viral eclipse images.

And, sorry if the size of the Moon seems disappointingly small, but it is small! This is what a lunar eclipse really looks like to correct scale.

By comparison, many lunar eclipse composites you’ve seen are made of giant moons shot with a telephoto lens that the photographer then pasted into a wide-angle sky scene, often badly, and pasted in locations on the frame that usually bear no resemblance to where the Moon actually was in the sky, but are just placed where the photographer thought would look the nicest.

You would never, ever do that for any other form of landscape photography, at least not without having your reputation tarnished. But with the Moon it seems anything is permitted, even amongst professional landscape photographers.

No, you cannot just place a Moon anywhere you like in your image, eclipse or no eclipse, then pass it off as a real image. Fantasy art perhaps. Fine. But not a photograph of nature.

Sorry for the rant, but I prefer accuracy over fantasy in such lunar eclipse scenes, which means NOT having monster-sized red Moons looming out of proportion and in the wrong place over a landscape. Use Photoshop to inform, not deceive.

Moonlight on the Prairie


The rising almost-Full Moon, a “Blue Moon” of July 30, 2015, rising behind a rustic old farmhouse near Bow Island, Alberta. The Moon sits in the pibk Belt of Venus with the blue shadow of the Earth below. This is a single frame from a 600-frame time-lapse sequence, taken with the Canon 6D and 16-35mm lens.

I present a short time-lapse vignette of scenes shot under moonlight on the Alberta prairie.

The movie linked below features sequences shot July 29 and 30, 2015 on beautifully clear moonlit nights at locations south of Bow Island, Alberta, on the wide open prairie. The three-minute video features two photogenic pioneer sites.

Circumpolar star trails over the historic but sadly neglected St. Anthony’s Church between Bow Island and Etzikom, Alberta. The Big Dipper is at left, Polaris at top. The Roman Catholic church was built in 1911 by English, Russian German immigrants. It served a dwindling congregation until 1991 when it closed. At that time workers found a time capsule from 1915 with names of the priest and parisioners of the day. In summer of 2014 the Church suffered its latest indignity when the iron cross on its steeple tower was stolen. It was there when I stopped at this Church on a site scouting trip in May 2014. I planned to return on a moonlit night and did on July 29, 2015. A nearby house had been torn down and the cross was now gone.  This is a stack of 300 6-second exposures with the Canon 6D at ISO 1600 and 16-35mm lens at f/2.8. Bright light from a 13-day Moon lights the scene, making for very short exposures. The ground comes from one exposure to keep shadows sharp. The final stars also come from another single exppsure taken two minutes after the last trail image. I used the Advanced Stacker Actions to stack the trails.

The church is the now derelict St. Anthony’s Church, a former Roman Catholic church built in 1911 by English and Russian-German immigrants. It served a dwindling congregation until as late as 1991 when it closed. At that time workers found a time capsule from 1915 with names of the priest and parisioners of the day.

The wood church seems to have been largely neglected since.

In the summer of 2014 the Church suffered its latest indignity when the iron cross on its steeple tower was stolen. I also shot in the pioneer cemetery of the Church.

Circumpolar star trails circling above an old rustic and abandoned house near Bow Island, Alberta, with illumination from the nearly Full Moon. Cassiopeia is near centre. Polaris is at top left.  This is a stack of 140 frames from a time-lapse sequence with additional frames added for the first and last stars, and the ground coming from a mean combine stack of 8 frames to reduce noise. Each frame is 10 seconds at f/4 with the 16-35mm lens and ISO 1600 with the Canon 6D. Stacked with Advanced Stacker Actions, using the Ultrastreaks effect, from within Photoshop.

The other site is a nearby farmhouse with photogenic textures and accompanied by rustic out buildings that are barely managing to stand.

Illumination was from a waxing gibbous Moon, just 1 to 2 days before the infamous “Blue Moon” of July 31. Its bright light turned the sky blue, and lit the landscape with the same quality as sunlight, because it is sunlight!


Enlarge the video to full screen for the full HD version.

For the technically inclined:

I shot the scenes with three cameras – a Canon 60Da, Canon 6D, and Nikon D750.

The Nikon, with a 24mm lens, was on the Dynamic Perception Stage Zero Dolly and Stage R panning unit, while the 60Da, with a 14mm lens, was on the compact Radian panning unit. The third camera, the 6D, with a 16-35mm lens, was on a fixed tripod for the star trail sequences and stills.

The music is by Adi Goldstein (AGSoundtrax.com), whose music I often use in my sequences. It just seems to work so well, and is wonderfully melodic and powerful. Thank you, Adi!

To process the several thousand frames that went into the final movie, I used Adobe Bridge and Adobe Camera Raw, supplemented by the latest Version 4.2 of LRTimelapse (lrtimelapse.com). Its new “Visual Deflicker” workflow does a beautiful job smoothing out frame-to-frame flickering in sequences shot in twilight under darkening lighting conditions. Thank you Gunther!

For the star trail sequences and the still images above I used the Advanced Stacker Actions from StarCircleAcademy.com. Unlike most other stacking programs, the Stacker Actions work from within Adobe Bridge and Photoshop directly, using the processed Raw images, with no need to create intermediate sets of JPGs. Thank you Steven!
