CELESTRON Reducer Lens .7x - EdgeHD 1100

CELESTRON Reducer Lens .7x - EdgeHD 1100

  • The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 1100 one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object
  • 5-element lens design
  • Maintains similar flat-field performance as native EdgeHD optical design
  • Increases field of view by 43% to better capture wide field images
  • Threads directly onto the 3.25" threads of the EdgeHD which reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders
  • Maintains the identical back focus when used at f/10 and provides generous back focus to accommodate additional accessories and wide variety of cameras
  • Allows use of existing EdgeHD T-Adapters with or without the Reducer Lens
  • Manufactured by CELESTRON, USA

Description

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.

Performance

  • Design: 5-element optical layout designed specifically for the EdgeHD 11" to maintain the flat-field performance of the EdgeHD optical design
  • Maintains the same back-focus as when used at f/10: Unlike generic reducers the EdgeHD .7x provides generous back-focus to accommodate additional accessories and a wide variety of cameras. Also allows use of existing EdgeHD T-Adapters and other Celestron imaging accessories
  • One full F-Stop faster than f/10: Reduces the exposure time by one-half to capture the same brightness of object
  • Increase field of view by 43%: Better for capturing wide field images of larger galaxies and nebulae

Glass

  • Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration
  • Fully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction
  • Blacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast

Full Frame Design

  • Threads directly onto the 3.25" threads of the EdgeHD optical tube: Reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders
  • Clear aperture: 60mm clear aperture lens optimized for a 42mm image circle for use with large CCD sensors.

Mechanical Design

  • Machined aluminum housing: Computer assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.
  • Threaded metal covers for both ends of the lens assembly: To protect your investment from unwanted dust and scratches.

Versatility

  • Fastar compatibility and f/2 imaging with optional accessory: the EdgeHD is the most complete imaging system in its price range.

    Battery Disposal

    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.



    Disposal of Energy Saving Lamps

    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:

    • If the lamp breaks inside a fixture, disconnect the fixture from the power supply first to avoid electric shock.
    • Ventilate the room thoroughly for 10–15 minutes and leave it during this time.
    • Avoid cutting yourself on broken glass. Use disposable or household gloves if possible.
    • Carefully collect all parts of the lamp, preferably by sweeping them up.
    • Use a damp disposable cloth or adhesive tape to pick up small fragments and dust.
    • If necessary (e.g. on carpet), use a vacuum cleaner.
    • Dispose of the vacuum cleaner bag or contents afterwards.
    • Place all lamp residues, cloths, etc. into a tightly sealed plastic bag or screw-top glass container.
    • Dispose of broken and non-functioning lamps at the nearest collection point for waste lamps.

    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.

    Tips to avoid accidents:

    • Always disconnect the lamp from the power supply before replacing it to avoid electric shock.
    • Allow the lamp to cool down before replacement.
    • Hold the lamp by the base or housing, not the glass tubes.
    • Wrap defective lamps in a soft cloth or store them safely until disposal.
    • Only remove the new lamp from its packaging immediately before installation.
    • Due to their mercury content, spiral energy-saving lamps must not be disposed of in household waste according to the Electrical and Electronic Equipment Act (ElektroG). Dispose of both broken and non-functioning lamps at the nearest collection point for waste lamps.
You will receive automatically after each purchase to your eBay specified email address a mail to initiate the purchase.

In the checkout process, you can combine multiple purchases from us and save shipping costs, adjust your billing and shipping address, the payment method and delivery. You will also find all the information about the payment, such as our account in case of bank transfer.
