The Celestron EdgeHD 1100 .7x Focal Reducer Lens transforms your telescope into an ultra-fast astroimaging system, cutting exposure times by half while expanding your field of view by 43%. Engineered with custom 5-element rare-earth Lanthanum glass, it delivers flat-field sharpness across large CCD sensors without sacrificing focal clarity. Perfect for deep-sky photography, this high-performance telescope focal reducer seamlessly integrates into your optical tube setup for stunning astrophotography results.
Designed specifically for the 11-inch EdgeHD optical tube, the Celestron EdgeHD 1100 .7x Focal Reducer Lens incorporates a computer-assisted CNC machined aluminum housing that guarantees precise alignment of all optical elements. Unlike standard field flatteners or generic focal reducers, this custom 5-element optical design preserves the award-winning flat-field performance of the native EdgeHD optical system while providing a generous 146mm back-focus to accommodate off-axis guiders, filter wheels, and full-frame camera sensors. Each air-to-glass surface features fully multi-coated optical elements with blackened lens edges to minimize internal reflections and maximize contrast, making it an indispensable upgrade for dedicated astroimagers.
How does the Celestron EdgeHD 1100 .7x Focal Reducer Lens affect exposure times?
The Celestron EdgeHD 1100 .7x Focal Reducer Lens makes your telescope optical system one full F-Stop faster, reducing your required exposure time by 50% to capture the same brightness of faint deep-sky objects.
Does the Celestron EdgeHD 1100 .7x Focal Reducer Lens work with full-frame camera sensors?
Yes, it features a 60mm clear aperture lens optimized for a 42mm image circle, making it fully compatible with large CCD and full-frame DSLR or dedicated astronomy cameras.
What is the required back focus for the Celestron EdgeHD 1100 .7x Focal Reducer Lens?
The optimal back focus for the Celestron EdgeHD 1100 .7x Focal Reducer Lens is 146mm (5.75 inches), giving you ample space to connect T-adapters, off-axis guiders, and filter wheels.
Can I use this Celestron EdgeHD 1100 .7x Focal Reducer Lens on other Celestron optical tubes?
No, this specific focal reducer is custom-engineered for the optical layout and 3.25-inch threading of the EdgeHD 1100 optical tube.
