Astrophotography

I recently moved into the world of digital photography when I acquired two Nikon D750 DSLR cameras. From time to time, I will post results here.


A composite picture of the passage of the International Space Station over Calgary on October 3, 2017. A one-second exposure was followed by a one-second gap. Notice how the object slows down as it moves further to the east and away from the viewing site. The last few streaks turn red as the ISS moves into the Earth's shadow and disappears.

The Moon on October 3, 2017, taken with the Meade 4" f/10 Schmidt-Cassegrain telescope. Photoshop CC was used to adjust the contrast and brightness.

The Moon on September 27-29, 2017, from Calgary.

Pictures of the rising Moon were taken every three minutes and combined in Photoshop CC with a landscape photograph taken before moonrise. This montage was acquired near Ardrossan, Alberta, on September 7, 2017, nearly two days after Full Moon.

Note that due to refraction, the Moon was compressed vertically as it rose compared to its appearance later in the evening.

One day after the Full Moon, moonrise near Ardrossan, Alberta, on September 6, 2017. Pictures taken five minutes apart were combined in Photoshop CC.

Pictures of the Full Moon were taken every five minutes and combined in Photoshop CC with a landscape photograph taken at moonrise. This montage was acquired at Calgary, Alberta, on September 5, 2017.

The Sun on September 7, 2017. Notice how the sunspots have moved compared to the image two days earlier, due to the Sun's rotation.

The Sun on September 5, 2017. A solar filter was used with a Meade 4" f/10 Schmidt-Cassegrain telescope. Photoshop CC turned the original grey image into a pleasing yellow depiction.

The Moon on May 29, 2017, taken with the Meade 4" f/10 Schmidt-Cassegrain telescope. This photograph was acquired in JPEG format, which lacks the dynamic range of a NEF (RAW) image.
