Above: Waning Crescent Moon at 5:53 AM CDT August 2, 2013 (10:53 UT), 8″ reflector telescope with 25mm eyepiece.

Below: Jupiter and its four largest Moons offer an ever-changing space-scape, though in the photo below you can’t see Io, which was transiting Jupiter’s face at the time.
From left to right: Ganymede, Europa, Jupiter, Callisto, 5:29 AM CDT (10:29 UT).

Below: 29 minutes later, the lightening sky helps me photograph Jupiter’s atmospheric cloud belts. 5:58 AM (10:59 UT):
When the sky is darker, the photometer on my cell phone camera tries to take in as much light as possible, resulting in loss of planetary detail due to overexposure. But the lightening sky floods the camera with light, causing the photometer to kick down the light level, revealing more detail. Just something I’ve learned as a low-budget astrophotographer. :O)

Jupiter photos with 8″ reflector telescope, 25mm eyepiece and 2x Barlow. All with LG VX8360 cell phone camera.

Saturn is very nicely placed for evening viewing after sunset during mid to late summer this year. Also, since it is currently at eastern quadrature (a fancy way of saying that the Earth and Saturn are at an especially wide angle from each other with respect to the Sun), it’s currently possible to observe Saturn’s shadow on the rings behind it, and I think I managed to capture a hint of it in the first photo below, even with my supremely modest equipment. It would be on the lower right portion of the rings adjacent to the planet in the photo.

Venus and Jupiter are the two brightest planets, and these days Jupiter is appearing as a brilliant “morning star” in the east before dawn, whereas Venus is appearing as a bright “evening star” in the west after sunset.

Beautiful skies like this one keep me getting up before dawn:

Today marks one year since the passing of our Pluto:

Above: Pluto with Mom and my great nieces and nephews, in a moment of perfect sweetness, just one hour before he died.

I find it appropriate and touching that the third anniversary of Pluto’s passing will be marked by a different kind of passing of a different kind of Pluto. Two years from now, barring some space disaster, the New Horizons spacecraft will be entering the vicinity of the (currently classified as) dwarf planet Pluto after 7 1/2 years of swift travel. The spacecraft will make its closest approach to Pluto on July 14, 2015. As a way of dramatizing and building anticipation for this momentous event, here’s a series of simulated images generated via one of my favorite online utilities, the NASA-JPL Solar System Simulator:

Above: Today Pluto remains a tiny dot as viewed from the spacecraft.

Below: The next six images dramatize New Horizons’ final approach during July 12-14, 2015. The elliptical path represents the orbit of Charon, Pluto’s largest moon:

Above: My extremely humble, unedited photo of the Sun with a dramatically large sunspot group currently visible. I could even see the largest spot using the eclipse shades we used for observing the May 20, 2012 solar eclipse. Read all about it and see some very sharp photos at Spaceweather.com.

At the neighborhood park, at dawn on July 3:
Above: A mother Mallard and half-grown ducklings heading towards the water.
Below: I was very pleased to see a mother Wood Duck with eight ducklings!
Photos above with 7×35 Bushnell binoculars.

Above: It’s amazing how much wildlife one can see so close to the city, and you see more by coming out at a quiet time such as the early morning.

Below: A very calm dragonfly, no doubt looking forward to a fine day of mosquito hunting.

It’s good to get down to the neighborhood park again. Once I was there once or twice a day, but not very often for almost a year. The park is full of memory for me, the memory of two thousand walks with Pluto during the last two and a half years of his long life. But life goes on, new ducklings and all!
