Oregon's 2017 August 21 Total Solar Eclipse Focus binoculars on distant terrestrial object, then project Sun's image onto white paper for safe eclipse viewing (orient larger lenses toward Sun; eyepieces toward paper). CAUTION: excessive projection intervals will generate heat sufficient to damage binoculars. http: //www. stgeorgeutah. com/news/archive/2014/10/22/ams-partial-solar-eclipse-steals-afternoon- sky-safetytips-viewing-locations-where-to-buy-glasses/#.
