Some Specs taken from Celestron Data Sheet:"Intergal 1.7X Large Apature Achromatic Barlow Lens to increase an f10 optical system to a f17 and a f6.3 system to f10.7.Multi-Coated Optics.Laser Aligned Prism for minimal image run-out.Consumes 60% less back focus distance that conventional diagonals;1" back focus required.
