In this video, we learn about eclipse phenomena to expect and how to record it from “Mr. Eclipse” himself, Fred Espenak, a retired NASA astrophysicist with the Goddard Space Flight Center in Greenbelt, Md.; and amateur-turned-professional photographer for the Toledo Metroparks, Doug Hinebaugh, who will be recording his first total eclipse; to the Ottawa National Wildlife Refuge’s manager Jason Lewis for what to expect from wildlife. 

For sorting through the clutter of useful companion phone apps for the eclipse, the professionals we spoke with recommend the Solar Eclipse Timer app available through solareclipsetimer.com.
