    Hello ZWO! Can this focuser be used on an 11 inch Celestron Rowe Ackerman Schmidt Astrograph (RASA)? It has a Feather Touch focuser now, but I would assume it would need a bracket.
    Will ASIAIR support any other electronic focuser like the Celestron electronic focuser?

    Regards,
    MC

      EAF supports Feather Touch focuser.

    Dear Sirs….

    Since you write the focuser supports Skywatcher reflectors etc, I was wondering if that includes Skywatcher Esprit series refractors. The focsuing system is basically the same as on their refractors as on the reflectors.

    Please add support for Explore Scientific ED80 APO (or higher aperture like ED102) telescopes. They are very popular telescopes. I have your whole wifi setup and I really wish I could add this last piece. Any plans for that in the near future? Thanks!

    Hi Sam
    Thinking on using it for motorizing the primary mirror collimation knobs, for a 500 mm D-K custom made telescope here, any comments on that? Is there some discount for buying three units? 😉

    Hello, it would be nice if somewhere you said with what models it is compatible, because seeing the comments of the social networks it turns out that there are many models of telescopes that are not compatible with this focuser.
