[edit]Made some minor English corrections. The constant in the denominator waas original 1.884 = (1.22)^2. 1.22 is a rough approximation to Rayleigh's criterion which to more significant digits is 1.21967... (the first zero of the Bessel Function if the First kind divided by pi). Square that number to get 1.48759... which is what I put in the original number's place. 157.185.95.25 (talk) 18:20, 18 October 2013 (UTC)mjd
