    Questions & Answers

    Ask a Question
    • Does this reducer work with Celestron C6?

      Yes, although the C6 might exhibit a bit more residual field curvature than the 8", so you will want to only use it with cameras with APS-C or smaller sensors. At proper 105mm spacing to the camera sensor, the scope will be at f/6.3 at a focal length of ~

    • Does this adapter replace the "Visual Back" on the telescope, or does it attach to the Visual Back or the Star Diagonal eyepiece holder on a Celestron 8" SCT?

      This attaches to the 2"-24 TPI threaded visual back on the telescope's rear housing. It will not attach to the rear of the 1.25" diagonal holder.

    • Can this focal reducer be used with 2" star diagonals and eyepieces?

      Hello Greg, It indeed can. I use my f/6.3 focal reducer on my 8" Celestron SCT & it works nicely for objects that look better with a wider field of view such as the Orion Nebula & the Andromeda Galaxy.

    • Will it fit to the back of my CPC 11,my opening is 3.25"

      The CPC 11 should come with a reducer that takes it from 3.25" down to 2" 24 TPI threads. It is on that part that the F/6.3 focal reducer fits onto.

    • What are the 5 eyepieces that are included?  Are they Kellners?  Plossls?  What are their focal lengths?

      The five eyepieces that are supplied with this telescope have the following focal lengths: 25mm 20mm 12.5mm 8mm 4mm They are all Huygens eyepieces except for the 4mm which is a Symmetrical Ramsden design.

    • Will this focal reducer work with a full frame camera on a Meade LX200>

      Unfortunately, no. Imaging standards were lower back in the film days when this reducer was created - plus film was more forgiving of off-axis coma than digital - so nowadays the f/6.3 reducer is only considered usable over the field of an APS-C format se

    • Hi, can I use this with the Baader click lock clamp on my CPC1100?

      You will need an adapter as this reducer will not natively fit. A 2" nosepiece to 2"-24 TPI SCT thread adapter like the JMI JM-ADPT2THREAD adapter or the FLI FL-DT-1 will let this reducer slide into the Click-Lock adapter. On the camera side, you will the

    • Would this work well for a NexStar 8SE for astrophotography with a Canon T5i and an Orion G3 Starshoot Color? An Antares f6.3 focal reducer corrector would be a better choice?

      The Celestron f/6.3 reducer is the best choice for both cameras
