    Default F3.3 and 6.3 reducer camera compatibility



    Hi guys,
    I have a 3.3 and 6.3 reducer for celestron c8 sct. What I would like to know is for each reducer, what imaging camera can I buy to give the widest
    field of view. I know of the newastro program and used it but am looking for comments from users. Looking for colour camera only.

    Regards
    Kon

    The f/3.3 reducer is intended for use with CCD (small chip) cameras, with a relatively short back-focus distance.

    The f/6.3 reducer/corrector is intended for use with APS-C and full-frame (35mm) or larger imagers - this includes most DSLR's.

    By definition, the f/3.3 reducer provides a wider FOV, but a smaller image scale.

    If the .33x reducer is originally for Meade telescopes you may have trouble getting it to work properly on a Celestron. It's a strong lens. The tolerances of where it should intercept the light cone are very strict, and Meade's and Celestron's tubes are not identical.

    The .63x reducers are interchangeable. They're good for photography because they flatten the field, widen the view and reduce the shutter time. I have a .63x by Celestron that I use on a C6. Visually, a .63x reducer is nice too because it will give you lower magnifications than you can't reach without it.

    I'm certain you'll like your scope at f/6.3, but I expect you may need some help to get it to function at f/3.3.


    Good luck!
