Description
This combination focal reducer and field corrector lens accessory works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C6, C8, C9 and C11 telescopes and f/7 for the C14 telescope.If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.
Celestron doesnt offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.
THE #94175 REDUCER/CORRECTOR LENS IS NOT COMPATIBLE WITH CELESTRON EDGEHD OPTICAL SYSTEMS.

Astromania 0.5X Reducer for Photography and Observing - 1.25" Filter Thread (28.5x0.75MM) on Both Sides - Reduces The Focal Length for Visual and Photographic Use
Feature
85mm focal length, reduction factor of about 0.5X, depending on spacing. 0.5x focal reducer effectively halves the focal length of a telescope, enabling lower magnification, a wider field of view, and shorter exposure times for astrophotography.2 lenses for better correction - cemented together and coated, black-anodized aluminum housing.
Mounting threads - 1.25" filter thread (28.5x0.75MM) on both sides: Threads into eyepieces, camera adapters, and other accessories with standard 1.25" threads, and can be stacked with additional 1.25" threaded accessories.
Free light transmission - 22.5mm lens aperture. Can be used with additional spacers (available separately) to achieve further focal reduction.
Intended for use with with longer-focal-ratio telescopes and eyepieces of narrow to moderately-wide apparent fields of view.
Description
Astromania 0.5X Reducer halves the focal length of your telescope, giving you a much wider field of view. You can use this, for example, for doing astrophotography using an astronomy webcam. Using the reducer is ingeniously simple - it is threaded for attaching to a 1.25" filter thread, which lets you easily screw it into any 1.25" eyepiece or 1.25" camera adapter. Screw the Astromania reducer into the filter thread on your camera and so double the size of the photographic image field. This lets you take images of much larger areas of the lunar surface, for example. The reducer is also great for taking videos of the Moon using your webcam. You can obtain even larger image fields with your astronomy webcam if you attach an extension tube (e.g. 25mm) between the reducer and camera.Screw the reducer into a 1.25" eyepiece and you have a smaller magnification and hence a significantly larger field of view. You can use the reducer if you don't have the correct eyepiece. The reducer is optimal for achieving a focal length of up to about 25mm.4. Celestron T-Adapter with SCT 5, 6, 8 with 9.25, 11, 14, Black (93633-A)
Feature
The Celestron T-Adapter attaches an SLR or DSLR camera to a Schmidt-Cassegrain telescope for prime focus photographyThreads on to the rear cell of Schmidt-Cassegrain telescopes
T-threads accept camera brand specific T-Ring (sold separately)
Description
To get started, youll need the appropriate T-Ring for your camera body (#93402 for Nikon & #93419 for Canon EOS). Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. Thats all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescopes focal length. For instance, a 300 mm camera lens is considered to be pretty powerful, right? Well, if you are using an 8 SCT at prime focus, youve got yourself a 2000 mm lens with a lot of light-gathering capability!5. Celestron Reducer Lens .7x - for EdgeHD 925, 94245
