Product Details

  • The Celestron .7x Reducer Lens makes your EdgeHD 1100 one full f-stop faster than f/10, reducing your exposure time by one-half to capture the same object brightness. It maintains a similar flat-field performance as the native EdgeHD optical design while increasing the FOV by 43% to better capture wide-field images.

    The EdgeHD reducer threads directly onto the 3.25-inch threads of your EdgeHD optical tube. This reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders. It keeps the identical back focus when used at f/10 and provides generous back focus to accommodate additional accessories and a wide variety of cameras.

    GAIN BETTER ASTRO-IMAGING AND VIEWING WITH THE CELESTRON EDGEHD 1100 .7X REDUCER

    • Quality Design: 5-element optical layout designed specifically for the EdgeHD 1100 to maintain the flat-field performance of the Edge HD 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. It 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.
    • 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.
    • Blackened Edges: All lens elements have blackened edges to minimize internal reflection and maximize contrast.
    • Full Frame Design: Threads directly onto the 3.25-inch threads of the EdgeHD optical tube. Reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders.
    • Clear Aperture: 60 mm clear aperture lens optimized for a 42 mm image circle for use with large CCD sensors.
    • Machined Aluminum Housing: Computer-assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.
    • Threaded metal covers for both ends: To protect your investment from unwanted dust and scratches.
    • Optimized Versatility: Fastar compatibility and f/2 imaging with optional accessory. The EdgeHD is the most complete imaging system in its price range.

The .7 focal reducer works well

I bought this reducer for my C11 edge and I don't have any complaints. It works as advertised and I am happy with it. The only down side is the price. $629.95 is a little steep and I have never seen this reducer selling for $ 997.95 anywhere. You aren't saving anything with the six hundred dollar price. How about a little honesty here!

Celestron .7X Reducer for EdgeHD 1100

Works great. I wish it did not cost so much. And I wish it was a f.63 instead of f.7. But it works as advertised. Note that it is heavy but that is the nature of the beast (lots of glass).

Very well put together

The reducer is very well put together with screw on lens covers on both ends. Very pleased with the quality and performance. I would highly recommend.
