That<br \/>\nThe aperture ratio changes to the same extent from 1:10 to 1:6.3.<br \/>\nThis results in a much larger field of view and around the<br \/>\nFactor 3 shorter exposure times. The optical correction system paves<br \/>\nthe slightly curved field of view of all Schmidt-Cassegrain telescopes.<br \/>\nThis is a fully corrected, vignetting-free &#8220;richfield&#8221;<br \/>\nfield of view of 24 mm in diameter.
