Questions & Answers

Paul G : Can you use this reducer with the 925 2" star diagonal?Roger H : Maybe I shouldn't answer this because I don't own the reducer yet. But since Celestron says it maintains the same backfocus with or without the reducer, I'd say yes, the star diagonal should work the same, just with a wider field and reduced focal length.

Review in progress.,..

It arrived intact, but I haven't had a clear night to test performance. I hope by early summer I can see how this reducer lens works

In Stock! Celestron .7 Reducer Lens for EdgeHD 9,25

I searched several online retailers for this reducer for my 9.25 Edge telescope. All of them other than Adorama did not have any in stock. In fact a major back orders were the name of the game. I was pleasantly surprised to find it still available at Adorama. What usually happens when there isn't enough stock those that still have a few gouge customers by increasing their buy price. I for one will not buy when this is the case. What I liked about Adorama is that they not only had stock but didn't increase the price just because they could. I haven't had the opportunity to use this reducer yet but am looking forward to that event. Thanks Adorama!

Before diving into the world of astrophotography, consider the Reducer Lens .7x - EdgeHD 925. This lens is specifically designed to increase your field of view by 43%, making it ideal for capturing wide field images of larger galaxies and nebulae.

The EdgeHD 925 reducer lens features a custom 4-element optical design, meticulously engineered to maintain the flat-field performance of Celestron's award-winning EdgeHD optical system. Unlike generic reducers, this premium lens ensures substantial back focus, accommodating a wide array of imaging accessories.

The high index optical elements of the EdgeHD 925 reducer lens include extra low dispersion and exotic Lanthanum elements. These elements are key in providing high contrast viewing and minimizing chromatic aberration, ensuring your images are clear and vibrant.

All air-to-glass lens surfaces of the EdgeHD 925 reducer lens are fully multi-coated. This feature ensures maximum light transmission and color correction, enhancing the quality of your astrophotography. The lens elements also have blackened edges to minimize internal reflection and maximize image contrast, further improving your viewing experience.

The EdgeHD 925 reducer lens boasts a computer-assisted CNC machined aluminum housing. This precise spacing and alignment of optical elements ensure optimal performance. Additionally, the lens assembly features threaded metal covers to protect your investment from dust and scratches.

The lens threads directly onto the 3.25" threads of the EdgeHD optical tube, reducing mechanical vignetting and allowing for use with larger (full frame) sensors and Off-Axis Guiders. The clear aperture of the lens is optimized for a 42 mm image circle, perfect for use with large CCD sensors.

With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes a comprehensive imaging system. This reducer lens is not only one full F-Stop faster than f/10, reducing the exposure time by half to capture the same brightness of an object, but it also maintains the same back focus as when used at f/10. This allows for the use of existing EdgeHD T-Adapters and other Celestron imaging accessories, making the EdgeHD 925 reducer lens a versatile addition to your astrophotography equipment.

Celestron EdgeHD 925 Features

  • The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 9.25" one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object
  • 4-element lens design
  • Maintains similar flat-field performance as native Edge HD 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
