Partial Sequence and Totality 2 - 2017 Total Solar Eclipse
This composition captures the entire total solar eclipse of August 21, 2017 in a sequence of partial phases and the corona during totality.
The partial phases where shot with a Vixen ED100SF refractor, a Thousand Oaks solar filter (Type 3), and a Nikon D810 DSLR.
The image of the corona was produced with an Astro-Physics 105EDT refractor and a Nikon D800 DSLR. The corona is a composite of 57 separate exposures (1/2000 to 2 seconds) combined and processed using Photoshop CC 2017 and Photomatix Pro 6.
The Moon appears darker than the sky because of the huge contrast between the Moon's disk and the very bright inner corona adjacent to the Moon. I've tried to preserve this visual impression in this image. A custom Curves layer was used to approximated the color to the dark blue sky.
The image above is available as a Custom Print.
