August 21, 2017 Total Solar Eclipse:  Hopkinsville Kentucky
15 different photos arranged to show the progression of the eclipse. The eclipse begins on the right side of the image and progresses to the left through totality and the waning partial phases.
     On August 21, 2017 my family and I were on site in Hopkinsville, Kentucky for the total solar eclipse.  This was the second total eclipse for my wife and I, and the first for my children and grandchildren.  I was fortunate to have contacted the Northwest Baptist Church a few months before the eclipse and got permission to park on their property to set up camera equipment.  The church property sets on a incline that gave a good 360ยบ view.  It was without a doubt the best place near Hopkinsville to see the eclipse.
     I have been preparing for this eclipse most of my life.  As a young fellow I had a passion for astronomy.  I remember when I was fifteen years old and looking through a astronomy book from my high school library.  The book had a chapter on the mechanics of solar eclipses, and a chart of solar eclipses that would occur between 1950 and 2050.  At the top of the chart was a map of the August 21, 2017 total solar eclipse.

Baily's Beads, August 21, 2017 Total Solar Eclipse: Hopkinsville, Kentucky
 the last hint of the photosphere as totality begins.  This phenomenon is named in honor Francis Baily who theorized that the beads seen at the beginning of a total solar eclipse was sunlight shinning through mountains on the moon, which indeed does create Baily's Beads. 

     I remember being so excited.  The path of the future total eclipse would pass only one-hundred miles north of where I lived at the time.  My mind when into overdrive.  I immediately started thinking, "I can see that one, its close to home."  I then realized that I would be sixty-two years old in 2017 and immediately thought, "I hope I live that long."  Well, as you can imagine my thoughts on age as changed drastically since that day, and yes, I did live to see the eclipse own August 21.

Inner Solar Corona:  Hopkinsville, Kentucky
Notice the solar flares at 2:00, 3:00 and 5:00 position.  Solar flares are plasma 
being ejected from the photosphere.

     No words can express the beauty and excitement of an event like a total solar eclipse, and no photograph can capture the extent of tonal ranges of the solar corona.  It is something that must be experienced in person and seen with ones on eyes.

August 21, 2017 Total Solar Eclipse,  Solar Corona:  Hopkinsville, Kentucky
The solar corona extends two to three times the diameter of the photosphere.  This image does not show the entire corona.  The latitude of the camera sensor cannot maintain a proper exposure from the inner corona to the out corona. 

     The photos here simply, do not even come close to what the eye can see in an eclipse.  The human eye can see a far greater range of values than a camera.  Some of the images here are single images, others are multiple images put together to give the viewer a more comprehensive view of what I saw with the naked eye. I can not stress enough, how captivating, and thrilling a total eclipse experience can be.  The next total solar eclipse in North America will occur on April 8th, 2024.  I am planning to there, and I hope you will do the same.

Penumbral Lunar Eclipse
February 10, 2017

    This is a composite of 5 exposure of last nights penumbral lunar eclipse. The sky had a thin layer of clouds, but it was not possible to expose for the wide range of values of the clouds. Thus I made different exposures to capture the various values of glowing clouds from the moonshine. 


Note: Though I am from Alabama, the term moonshine here refers to the light of the moon, not the home grown elixir made from corn.

Lunar Eclipse

 
 
October 8, 2014,  Lunar Eclipse (partial phase)
shot from the campus of Oakwood University.
This image was shot through a thin layer of clouds

     I was up early this morning to photograph the total lunar eclipse, but the weather was not very cooperative.   I arrived on the campus of Oakwood University, (where I teach) where I shot this image.  The weather was very cloudy at my house, but was supposed to be better further west.  When I arrived on campus the sky was much better. However, soon after taking this image, the sky worsened, and the remainder of the eclipse was obscured by clouds.    Perhaps I will have better luck in April, 2015

Upcoming Lunar Eclipse


    On October 8th, North America will be treated with the second lunar eclipse of the year.  This is the second eclipse of a tetrad (four total lunar eclipses in a series). The last two eclipses will be April 14th, and September 28th, (2 days before my birthday) 2015.  The first of the tetrad took place on April 15th, 2014.  It was cloudy here in North Alabama and I did not get to see that eclipse.  If the weather permits, I will see this one.  This animation shows how the Earth's shadow crosses the lunar disk during the October 8th eclipse. The animation is from wikipedia.  For more details go to:

     I hope to get lots of good photos of the eclipse.  I'll keep my fingers crossed and hope for clear skys.
