Andrew Lowe's Astrophotography

Andrew Lowe's Astrophotography

I recently moved into the world of digital imaging when I acquired two Nikon D750 DSLR cameras and a RunCam Night Eagle 2 video camera. From time to time, I will post results here.

A recent move to Pemberton Heights, North Vancouver, may not have been the smartest choice for astrophotography, especially during the winter, but last night the skies cleared and I finally had a chance to image Comet 2022 E3 (ZTF). Our street has the benefit of no lights, and I was impressed with the ability of Photoshop to pull the data out of the sky glow.

On the left is a stack of five consecutive unguided two-second exposures with a Nikon D750 at ISO 800 and AF-S Nikkor 35mm lens at f/1.8, on Jan. 29, 2023 at 1:17 AM PST. Ursa Major (Big Dipper) and Ursa Minor (Little Dipper) are outlined; the comet is circled. On the right is a stack of five consecutive unguided two-second exposures with a Nikon D750 at ISO 800 and a Sigma 135mm DG lens at f/1.8, at 1:33 AM PST. A faint tail extends upwards from the comet.

Starlink G4-15 soars over Calgary like a string of pearls in this photograph taken at 10:59 PM MDT on May 16, 2022. Launched from Cape Canaveral Space Force Station on May 14 at 20:20 UTC, the individual satellites are still closely tracking each other.

Half-second exposures were recorded every second with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.

As predicted, clouds started to build up over Calgary a few hours before the start of last night's total lunar eclipse. My plan to drive as far east as possible changed when I saw better conditions to the north. I finally ended up about 50 km north of Hanna, pulled over on the side of Highway 36.

The clouds thinned for ten minutes at the end of totality, allowing me to take three exposures five minutes apart before the clouds moved in again.

The first picture, taken two minutes before the end of totality, shows the northern part of the Moon deep within the Earth's shadow. Five minutes later, the Moon has started to move out of the shadow. A final picture, seriously affected by cloud, shows the progression of the eclipse.

I used a Nikon D750 at ISO 800 and Sigma 135mm DG lens at f/1.8 and 1/2-second exposures, with Photoshop processing.

Less than three days after a total solar eclipse over Antarctica, the Moon has reappeared in the evening sky. Here it is in conjunction with Venus on the evening of December 6, 2021, at 5:29 PM MST, as seen from Calgary, Alberta.

I used a Nikon D750 at ISO 800 and Sigma 135mm DG lens at f/1.8 and a 1/20-second exposure, with Lightroom processing.

Venus is climbing higher in the sky after sunset, and has been recently joined by two other planets. This was the view from Calgary, Alberta, on December 5, 2021, at 5:44 PM MST. Venus is the bright object to the right, while Jupiter shines in the upper left-hand corner. Saturn is near the center of the image.

This is a stack of five consecutive 1/4-second exposures with a Nikon D750 at ISO 800 and AF-S Nikkor 35mm lens at f/1.8, with Lightroom and Photoshop processing.

The sky cleared over Calgary, Alberta, just before the start of the partial lunar eclipse on the morning of November 19, 2021. I took pictures every four minutes with a Nikon D750 at ISO 800 and a Sigma 135mm DG lens. Exposures varied throughout the eclipse.

This five-picture photomontage, from left to right, shows the Moon moving into the Earth's shadow. At mid-eclipse, the Moon was almost completely in the shadow except at the southern tip. The last two images show the Moon exiting the Earth's shadow.

The outline of the Earth's shadow shows well in this rearranged five-picture photomontage.
I recorded a poor display of the Aurora Borealis on the evening of October 12, 2021, at the Sibbald Creek Trail exit, near Calgary, Alberta. The sky darkened as the Moon set.

237 consecutive 13-second exposures from 10:09 to 11:31 PM MDT were recorded every 15 seconds with a Nikon D750 at ISO 800 and AF-S Nikkor 35mm lens at f/1.8, then processed and combined in Lightroom and Photoshop.

This comparison of my recent raw image of the southern Milky Way and the processed version shows the power of Lightroom and Photoshop. I used Lightroom to adjust brightness, color, contrast, lens distortion/vignetting, sharpness, and a few other tweaks. I imported the adjusted image and two others in Photoshop, aligned and stacked them, eliminated the lights from the adjacent highway, then applied a final round of brightness, contrast, and color correction.
While I was shooting the Perseid meteor shower with my wide-angle lens, I used my regular lens for a series of guided shots of the evening sky. Here is the Summer Milky Way at 11:45 PM MDT on August 12, 2020. Jupiter and Saturn are prominent to the left.

My viewing site was at Range Road 54A, Township Road 252, 2 km east of the Sibbald Creek Trail exit, near Calgary, Alberta.

Three consecutive 30-second guided exposures were recorded every 34 seconds with a Nikon D750 at ISO 800 and AF-S Nikkor 35mm lens at f/1.8, then processed and combined in Lightroom and Photoshop.

The International Space Station (ISS) is currently at an altitude where it completes 31 revolutions every 48 hours. Consequently, the ISS has a passage very similar to the apparition two days earlier. Its appearance was recorded on the evening of July 28, 2020, at 11:19 PM MDT. The overexposed Moon is prominent at the center-bottom. Jupiter is visible to the left. The ISS disappears on the left side as it passes into the Earth's shadow.

On the evening of April 27, 2020, the Moon occulted (passed in front of) a number of stars. I used my Meade 4" f/10 Schmidt-Cassegrain telescope with a f/3.3 focal reducer and a RunCam Night Eagle 2 video camera to record the events. Each video field is stamped with the precise time from an IOTA-VTI GPS Video Time Inserter. These images are stacks of five consecutive frames, so the time stamp is smeared.

There are two stars in the first image. Their disappearances occurred 63 seconds apart.

Click here for a rendered video from the third event involving the star ZC 983 (visual mag. = 6.0), which starts ten seconds before the disappearance and ends 15 seconds later. Analysis of the individual fields acquired every 0.0167 sec. gives the time of the event as 05:45:42.78 UTC. The other star passed north of the Moon.

The passage of the International Space Station (ISS) over Calgary, Alberta, was recorded on the evening of March 25, 2020, at 9:27 PM MDT. The bright object in the field is Venus. Auriga is centered in the frame, while Orion and Taurus are off to the left.

One-second exposures were recorded every two seconds with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.

In contrast to the ISS passage three nights earlier, this sequence was shot in heavy twilight, so the exposures are shorter, the ISS is not as trailed, and few stars are visible.

1/30-second exposures were recorded every two seconds with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.

The International Space Station (ISS) transited the Sun on April 25, 2019, at 12:33:22.94 PM MDT, as seen from Calgary. I shot high-definition video at 60 frames/second with a Nikon D750 at ISO 100 and 1/1000-second exposure with the Meade 4" f/10 Schmidt-Cassegrain telescope and solar filter.

The ISS was 528 km away and some detail of its shape is evident here. As seen in the second image (courtesy of transit-finder.com), my location was 1.95 km north of the centerline, so the ISS track was displaced towards the Sun's southern limb. The processed video has been slowed down by a factor of six.

The color-corrected photomontage (showing every second frame from the original video) was created with PIPP, Lightroom and Photoshop.

The International Space Station (ISS) transited the Sun on December 22, 2018, at 2:50:48.2 PM MST, as seen from Calgary. I shot high-definition video at 60 frames/second with a Nikon D750 at ISO 100 and 1/1000-second exposure with the Meade 4" f/10 Schmidt-Cassegrain telescope and solar filter.

The Sun was only 10o above the horizon and seeing conditions were poor. The ISS was 1466 km away, so little detail of its shape is evident here. As seen in the second image (courtesy of transit-finder.com), my location was close to the centerline, so the ISS track was nearly central across the Sun.

The color-corrected photomontage (showing every fifth frame from the original video) was created with PIPP, Lightroom and Photoshop.
