The best way to watch an eclipse is under clear sky. Beyond that I find that being in a seated position is not a bad idea either. This prevents one from blocking the view of others (I am 6'8" and am keenly aware of these sorts of things) and from tripping over a tripod (nerd fight).
So this leads one to question what exactly is the best chair for watching an eclipse. Well, again the answer is not all that straight forward since it depends on how high up the eclipsed Sun is during totality and whether or not you have equipment such as a camera to operate.
|Deck chairs work great|
|Don't block the view!|
|Just watch with automated cameras|
