Three Planets and the Moon

A few days ago the waxing crescent Moon joined the planets Mercury, Venus, and Mars in the evening sky. A few clouds and the reflection of the evening sky in the lake added a bit of color to the scene.

Afterwards, I stayed around to watch the rocket launch described in the previous post.

Venus and Mercury in the Evening Sky

Venus and the Pleiades star cluster are prominent in the center of the image while Mercury is about to set in the low gap. The zodiacal light is also faintly visible.

Next week the crescent Moon will join the group.

Moon, Mercury, and Pleiades in the Evening Sky

A few days ago the Moon, Mercury, and the Pleiades were all located close to each other in the evening sky. Although it had been completely cloud free all day, some high clouds moved in right after sunset. I think they add a bit of interest to the otherwise clear sky.

The image is a composite of a 2-second image of the sky and an 8-second image of the water. 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 second image is a screen shot from the Stellarium application showing the positions of these three objects in the evening sky. In addition, Stellarium can project a box showing the field of view of lenses with various focal lengths. In this case, this is the FOV for a 70mm lens. I often use this feature to determine which lens or focal length will give the best framing.

Conjunction of Venus and Mars

As mentioned in the previous post, the planets Venus and Mercury passed very close to each other in the evening twilight sky a few nights ago. In fact, this conjuction is the closest conjunction of these two planets until 2033. I chose to photograph the two planets the night before closest approach as I was interested in getting a bit of separation of the two in both the sky and their reflections in the water.

The first image was taken at 2025 MST 27 May 2021 with an 85mm focal length. The second image was taken a short time later at 2035 MST with a focal length of 120mm.

In the first image, there is a very nice and long reflection of Venus in the water; the reflection of Mercury is also present but is faint and diffuse. In the second image, the planets were just a few minutes away from dropping below the ridge to the northwest. In this image, the reflections of both planets are easily seen.

The weather cooperated nicely with light winds allowing reflections on the smooth water of Upper Lake Mary.

 

The Moon and Two Planets in the Evening Sky

Yesterday (12 May 2021) provided an opportunity to view the thin crescent Moon very close to the planet Venus. Also visible in the evening twilight sky was Mercury higher above the pair.

For a few months each year, it is possible to be located so that the setting of the 1-day old crescent Moon aligns along the length of Upper Lake Mary. This allows for a long fetch of water in which to get reflections of the Moon and planets. Of course, this only works if it is not windy and spring is our windy season. So it was very nice to have both clear skies and very light winds for this event.

In the above image the crescent Moon is just slightly above and to the left of Venus. Near the top center of the image is Mercury. Venus is still rising higher in the sky each day while Mercury is dropping lower. Later this month they will pass by each other with ~0.4° of separation. That should be another interesting event to photograph.

Two days earlier there will be a total Lunar eclipse taking place in the pre-dawn hours.
