It allows to fit different eyepieces into the scope. 2" eyepieces are not the standard on most new scopes and 2" eyepieces naturally give wider field of view. I finally go some 2" eyepieces last week but only after 9 months worth of research and testing with other observers. Very handy to join an Astro Club as they can help in a much better more practicle way.
