Fitting all four objects in the image was the goal and I was successful. Venus and Mercury were below and the star Antares was to the left.

The next evening the Moon was 4% illuminated and higher in the sky making it an easy target. Venus and Mercury set behind Cathedral Rock. If you look carefully at the image and above the two people, you can just barely see a very thin crescent in the gap. It was only 1% illuminated in a bright twilight sky. A very thin crescent Moon sets behind Cathedral Rock.īut, wait! A closer inspection of the images shows that I did capture the crescent Moon. I never was able to see the crescent Moon. Venus and Mercury would also be visible.Īh, if only is was as easy as that. A check of The Photographers Ephemeris indicated that I could set up at Little Horse trailhead near Sedona and capture the thin crescent as it slipped between the spires of Cathedral Rock. On Monday and Tuesday (28-29 October 2019) the thin crescent Moon passed near the planets Venus and Mercury in the evening twilight sky. Post processing included large values of Unsharpen Mask to help sharpen the dimmest stars and Pluto-with the undesired side effect of creating halos around the brighter stars. The best images were stacked to reduce noise.

Images were shot at f/2.8, ISO 1600, and 30s. As a magnitude 14.3 object, this was near the limit of what could be resolved with my Nikon 180mm AI-s f/2.8 lens shot wide open. I used Stellarium as a guide to hopping from one star to another-comparing the photographs with Stellarium star charts-until I finally located Pluto.

However, Pluto and Mars passed very close to each other (~10 arc minutes, or less than the diameter of the Moon) on 23 March 2020 making it easier to find one based on the location of the other. 14.3) for me to find with my camera/lens setup. So I thought it would be interesting to photograph Pluto. Stellarium star chart showing positions of the planets in the morning sky.

Nestled in between these bright planets lies the minor planet Pluto. These are all bright and easily visible even during twilight hours. Four Planets in the Morning Skyįor several weeks the planets Mars, Jupiter, and Saturn have been visible in the same portion of the morning sky. I often use this feature to determine which lens or focal length will give the best framing. In this case, this is the FOV for a 70mm lens. In addition, Stellarium can project a box showing the field of view of lenses with various focal lengths. The second image is a screen shot from the Stellarium application showing the positions of these three objects in the evening sky. It was a breezy evening and the water was roughed up a bit by the wind but the longer exposure helped to smooth out the surface and provide a bit of a reflection of the Moon. The image is a composite of a 2-second image of the sky and an 8-second image of the water.

Screen shot from Stellarium showing the evening sky plus the field of view from a 70mm lens. I think they add a bit of interest to the otherwise clear sky.

Although it had been completely cloud free all day, some high clouds moved in right after sunset. A few days ago the Moon, Mercury, and the Pleiades were all located close to each other in the evening sky.
