Product Info
Manufacturer 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, C9¼ 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 doesn’t 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.
Product carries two year factory limited warranty (within US/Canada only).

Pros: Cons: Comments:Bad weather has prevented me from using this item so I'll comment on Agena Astro Products. I've recently purchased a new scope and purchased quite a few quality accessories from four different companies to complement the scope. Agena Astro Products became my favorite of those companies and I'll give them first consideration for any future purchases. Quick shipping, good packing, friendly service and no second-rate, defective, returned or previously used products from AgenaAstro like I received from some of the other companies. Thank you!

Oct 17, 2018Worked as expected. A happy owner.
Pros: Cons: Comments:Focal reducer works perfectly with my C6. Now I can have a shorter focal length on scope. Also Perfect for my basic wider view astrophotography..

Sep 20, 2018Very happy
Pros: Cons: Comments:After a lot of research and reading lots of reviews to compare the Celestron with other brand products that apparently come out of the same factory, I decided to pay a bit more to get the Celestron one. I'm not disappointed. Nice clean optics, good looking coatings and does the job beautifully. Also super happy to find it had been opened and inspected by Agena's team before they shipped it to me.

Mar 28, 2017Very pleased with product
Pros: Cons: Comments:I have 10 or more hours of observing deep sky objects using this product under dark skies. It performs as advertised by Celestron. Wider FOV and flatter field. This relatively inexpensive lens has given new life to my old 8" f/10 SCT due to the wider, flatter field of view at f/6.3.. I leave it attached to the 2" visual back on the scope for almost all of my viewing.

Sep 6, 2014Still the Best R/C for SCTs
Pros:Quality Lenses,Strong Construction,Lightweight,Accurate
Cons: Comments:There are several reducer correctors out there, but Celestron is still the best, IMO. If you want to use 1.25" eyepieces and a 1.25" diagonal, this is the reducer to get. You can use this with 2" accessories, but you may experience some vignetting and effective aperture loss. IMO, views in my C8 with the reducer/corrector along with a 1.25" prism, SCT style diagonal and a 24mm Explore Scientific 24mm 68 degree eyepiece gives the best corrected, widest field views possible without vignetting or aperture loss.

Jun 30, 2007Great accessory for Deep space imaging and viewing
Pros:High quality, excellent performance
Cons:None
Comments:These are designed to be used with an SCT to help shorten the focal length and correct some of the field curvature in the SCT design. The Celestron brand F6.3 is similar to the Meade version....and the Meade version was a few dollars cheaper but not by much. I got the Celestron reducer used. I really had no bias between the Celestron or Meade versions....however, supposedly some Meade versions were sold with a defect which has since been corrected.
Bottom Line: Would you recommend this item? Yes
The F6.3 reducer/corrector does its job well and can be used also for visual observing of deep space objects which is a huge plus. It works exactly as advertised and I have been happy with it. I have used it in front of a Meade 644 flip mirror and with a Canon 350D attached to the back of the flip mirror and have not noticed any real problems with vignetting. Also, the stars on the edges of the field of view don't show much in the way of coma distortion which is good too.
Overall, this is an excellent quality focal reducer/corrector that does exactly what it is supposed to, and helps provide bright, wide-field views when visual observing.
Definitely recommended for observing nebula and galaxies as well as for astrophotography.Sort bySpecifications
