The video of the Total Eclipse was taken at Cardwell Cellars winery near Corvallis, Oregon on August 21, 2017. Totality was at 10:15 AM.
The video was taken using a Sony alpha 99 full-frame 23 mega-pixel digital camera with a 70-400 mm telephoto. All photos were taken at 400 mm. The photos taken before totality required a neutral density 100000 filter to protect the sensor. However, during totality the filter and the protective eyeglasses had to be removed to see the corona.
I did not have an automatic tracker and had to manually adjust for the motion of the sun across the sky. That is why the image jumps around so much. There were also some aberrant images from inside the lenses of the camera in some shots. I did not have time to figure out how to eliminate these.
In the video I have blocked the background sound until just before totality. The loud excited voices are those of my daughter Karen and her husband Tom and some for Sally and me.
Still photos. Before totality was taken of a field, the vineyards and the owners house in normal sunlight. At total eclipse shows how much darker the view is during the total eclipse. At 50% totality the group watching the eclipse with protective glasses. The two at the left are my brother and sister-in-law Ken and Sandy. The person in the center is Tom, the person in the black sweater is a visitor, and the guy in blue is me. David Comings photographer with my Sony.
The corona. There is a lot of science about the corona hidden in this video and the photos. For example, in the video, when Karen says “I can’t see the corona with my camera,” that was because she had not yet taken the filter off. This is also apparent in video when the last bit of sunlight disappears - the photo is totally black. It is not until I took the filter off that I could see the corona. Also people watching with just the glasses found they had to take them off to see the corona. Another measure of the relative brightness of the sun versus the corona is shown in the landscape photos before and at totality. Despite of seemingly bright corona the landscape is in almost total darkness indicative of the relatively little light from the corona. That is why the corona can only be seen during a total eclipse.
