Justin Suttles took his photos using a piece of welding glass.
NASA.gov recommended welders glass of shade 12 or higher, much darker than the filters used for most kinds of welding.
“If you have an old welder’s helmet around the house and are thinking of using it to view the Sun, make sure you know the filter’s shade number. If it’s less than 12 (and it probably is), don’t even think about using it to look at the Sun,” the agency advises.
A little further south, in Charleston, SC, within the path of the eclipse totality, where sun was completely eclipsed, Warwick’s Jason Major viewed the eclipse and recorded the event with his usual skill. You can have a look at his photos of the 2017 eclipse on Lights in the Dark.
