Celestron’s EdgeHD reducers feature a custom 5 element optical design engineered to maintain the flat-field performance of our award-winning EdgeHD optical system. Unlike generic reducers, our premium reducers provide substantial back-focus to accommodate an assortment of imaging accessories.
EdgeHD reducers offer high-index optical elements, including extra-low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air to glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Large diameter lens elements, up to 60mm clear aperture, ensure that the optimized image circle remains at a generous 42mm for use with large CCD sensors.
Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design.
With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today.

The following information is intended for users of batteries or rechargeable batteries, as well as products containing built-in batteries or rechargeable batteries, who do not resell them in the supplied form (end users):
1. Free return of used batteries and rechargeable batteries: Batteries and rechargeable batteries must not be disposed of in household waste.
You are legally required to return used batteries and rechargeable batteries to ensure proper disposal. You can hand in used batteries and rechargeable batteries at municipal collection points or local retail stores. As a distributor of batteries and rechargeable batteries, we are also obliged to take them back, limited to those types that we have or have had in our product range. You may either send such used batteries and rechargeable batteries back to us (sufficient postage required) or return them to us free of charge in person.
2. Meaning of the battery symbols
Batteries and rechargeable batteries are marked with a crossed-out wheeled bin symbol (see below). This symbol indicates that batteries and rechargeable batteries must not be disposed of in household waste. For batteries containing more than 0.0005% mercury, more than 0.002% cadmium, or more than 0.004% lead, the chemical symbol of the respective heavy metal will appear below the bin symbol: “Cd” stands for cadmium, “Pb” for lead, and “Hg” for mercury.
What to do in case of a broken lamp
Energy-saving lamps contain a very small amount of mercury. However, under normal use they are completely safe. No mercury can escape during or after operation. The only situation where mercury may be released is if the lamp breaks. In this case, small amounts of mercury vapor may slowly evaporate into the air at room temperature. The concentration is very low and well below legal safety limits in Germany. Broken energy-saving lamps must be disposed of properly, just like intact or non-functioning ones. Please follow these instructions:
What you should do:
What you should know:
Inhalation of mercury vapor is the most common way mercury enters the body. However, you have enough time to clean calmly, as mercury evaporates very slowly at room temperature. Broken glass fragments may still contain mercury, which can evaporate over time indoors. The measures above effectively prevent this. If fragments are carefully collected, sealed in a plastic bag, and stored outside the living area until disposal, no mercury exposure will occur indoors.
How to avoid lamp breakage:
Whether incandescent, halogen, or energy-saving lamps – breakage can never be completely ruled out, especially during replacement.
