Swan, Whirlpool, Wild duck, Uranus, and a nice Edge on galaxy.

During the third week of July our family visited the Grand Teton National Park, to relax and enjoy the magnificent beauty of nature. In the past I have wandered down to Jackson lake near Colter Bay, to view the night sky, where as far as I can tell there is no light pollution in any direction. The view really takes your breath away. The sky is filled with the Milky way and so many stars that the constellations seem to dissolve among the myriads of distant suns that fill the sky overhead. It has to be experienced to be understood. No description can adequately describe the view.

I was able to image a few objects before our vacation. Several roadblocks prevented me imaging after our vacation. The moonlight began to interfere with the full blue moon making its appearance at the end of July. Also the software I am using on my video camera was updated and I am going through a learning curve getting it to work the way I want. Below is a few of the objects that I imaged earlier in the month of July

 This is Messier 17 the Omega Nebula, also called the Swan Nebula, in the constellation of Sagittarius. It is an emission cloud receiving its light from  an embedded star cluster. This type of  material is what stars are made from.
 This gorgeous Spiral Galaxy called the Whirlpool Galaxy  in the constellation Canes Venatici. It shows a long arm connecting it to a smaller galaxy nearby. The Spiral arms are are clearly visible in this image suggesting rotation of the Galaxy in space.
Messier 11, also called the Wild Duck Cluster, and is a loose star cluster in the constellation of Scutum.
 This Edge on Galaxy NGC 7814, is located in the constellation of Pegasus. You may notice the dark lane passing through the center of this galaxy. This is obscuring dust clouds hiding the stars in the central region of this galaxy.
This is the Planet Uranus, the seventh planet of our solar system. It is shown here with several of it's moons. The diameter of Uranus is about 16000 miles, nearly twice that of earth. It takes 84 of our years to circle the sun one time. It is composed mostly of Hydrogen and Helium. It was discovered by William Herschell on March 13, 1871. A few days later he observed it again and thought it was a comet because it had moved slightly against the background of the stars.
