New Images (4/18/2014)

Total lunar eclipse April 15, 2014.  Total lunar eclipses occur when the moon passes through the earth's shadow.  This can only occur during the "full"moon, but does not happen every month because the moon's orbital plane is tilted related to the earth's.  However, lunar eclipses do happen according to a regular schedule, and this one was the first of 4 that will occur over the next 18 months.  This phenomenon is called a tetrad.  To learn more about lunar eclipses go to Wikipedia.  For a gallery of images of this eclipse see's page.
These images were made from
about 12:55 am to 4:30 am on April 15, 2014.  I used a Canon 50D camera mounted at prime focus of a Takahashi FSQ106N refractor (f/5).   Final processing  was done in Lightroom5 and  Photoshop.  Click the thumbnails below for additional images of the  eclipse.

This page illustrates what can be photographed using  amateur telescopes and a CCD camera.  I currently use an SBIG STL11000M camera and have previously used a SBIG and Starlight Xpress cameras, as well as a Cookbook 245 camera that I built myself. Most of the images were actually taken from my backyard near a busy street with several street lights. Not only is the CCD camera a great imaging tool, but it allows "real time" observation of objects not normally visible in areas with moderate-severe light pollution.
