Celestron EdgeHD 1100 0.7x is a focal reducer designed to complement the Celestron EdgeHD 11" optical tube, enabling a field of view that is over 40 percent wider than the field of view of the telescope itself.

The optical system of this reducer is a quadruplet with an air gap and low-dispersion elements made of lanthanum glass. To ensure the highest image quality, the lens surfaces are covered with a full multi-layer coating (FMC), and their edges are additionally darkened, which helps minimize the risk of internal light reflections and significantly improve contrast.

The outer casing is made of durable CNC-machined aluminum alloy. The set also includes metal caps to prevent dust and dirt from entering during transport and storage of the reducer.
