The image shown above uses a technique known as HDR or High Dynamic Range imaging. This specific image of the eclipse was made by combining 11 different shots with exposure times ranging from 1/4000th of a second to 1 second. This enables one to see the subtle detail in the corona and clearly shows how the hot gases in the Solar corona follow the magnetic field lines of the sun - reminiscent of the way in which iron filings will trace out the field around a magnet.

The Total Solar Eclipse 2017 as seen from Idaho Falls, Idaho on August 21, 2017. This spectacular event was only 1minute 41 seconds in duration but what a 1 minute and 41 seconds! Under nearly perfect skies the corona was exceptionally bright. The frames on the left and right show ingress and egress "Diamond Rings" (1/1000 s exposure) while the center frame (1/2 s exposure) shows streamers in the solar corona. Also visible in the image on the left are numerous solar prominences. Without the aid of a solar telescope and H-alpha filter (see last week's image for example) the only way to see prominences with the un-aided eye is to view them during an eclipse.
