The waxing 2-day-old crescent Moon setting over the front range of the Rocky Mountains in southern Alberta, as seen from the Rothney Astrophysical Observatory, April 6, 2019. Earthshine is visible on the night side of the Moon. This is an HDR blend of 5 bracketed exposures with the 200mm lens at f/2.8 and Sony a7III at ISO800. Blended with ACR. The exposure range captures the dark foreground without blowing out the bright sky and Moon. I applied luminosity masks for local adjustments to sky and ground. I added a mild Orton glow effect to the ground and clouds for artistic effect.
The ISS (Space Station) flies past the Pleiades star cluster, with reddish Mars below, and the larger Hyades star cluster at left with the reddish star Aldebaran. This was March 30, 2019, looking west into the evening twilight sky. The ISS was rising out of the west and twilight glow, climbing up the frame here. The sky gradient is from twilight and the Zodiacal Light in the west. Canadian astronaut David St. Jacques was on board at this time in early 2019. This is a stack of 3 x 3 minute tracked exposures for the background to smooth noise, mean combined, plus the single 3-minute exposure with the ISS, layered in with Lighten blend mode, all at f/3.5 with the Sigma 50mm lens and Canon 6D MkII at ISO 200. High haze and clouds added the star glows. though I also added an Orton effect layer to boost the star glow effect. I used the app GoSatWatch to preview the path of the ISS and plan the framing and timing.
