Total Lunar Eclipse 2015-09-28

Here is an animation of the eclipse from the start through mid-totality.


These images were taken with a Nikon D600 camera and a 25 year old Nikon 300 mm f/4.5 lens. All exposures were made with a lens aperture of f/8 and ISO sensitivity of 200. Exposures prior to totality used a shutter speed of 1/125 second, allowing you to see how the Moon darkened as it entered the penumbra. The shot at the start of totality (where the lower limb of the Moon is quite bright) used a shutter speed of 1/4 second, while the remaining two images of totality used a one second exposure.

I have aligned, rotated, and stacked the images while preparing the animation with The Gimp, taking out the apparent rotation of the Moon due to the Earth's rotation as the eclipse progressed.
