    Lightbulb Celestron AVX



    Hello,
    I'm considering buying an AVX mount.
    Can someone tell me how far that goes over the meridian, is there a mechanical or software stop?

    Hello Stefan,

    This is configurable by the user with R.A. slew limit settings.

    Also, the Meridian menu will allow the user to determine how the mount will approach objects close to the meridian. Options are Favor Current, Favor West, Favor East, or Disable.

    Hello Bryan,
    Unfortunately that does not answer my question.

    I own the AVX and there is no mechanical stop. Before I put my scope on this mount I rotate both axes several times around (multiple 360s) to "lube" up the bearings. Once your gear is attached though, at some point your gear may get in the way of doing 360s. Myself, I try not to go much over 3-4° past the meridian before I switch sides. For AP I'm not really sure if this behavior is needed. It is a holdover from my old visual days with a large Newt attached to an old Cave EQ mount. The reason you didn't let the OTA get much past the meridian was that it put the EP in a very awkward position.

    It does have a software stop configurable in the HC as Bryan mentioned above.

    Does this answer your question?

    I'm curious why are you interested in this capability?

    Cheers,
    JT

    Because I'm doing astrophotography and basically do not meridianflip. Drum should go over the 2 hours, better 3 over it. But I have decided now for an EQ8.

    This one?

    I don't see it mentioned that it will track 3 hrs past meridian..
    The only mounts that I know of that will go 2-3 hrs past meridian, are the CGX and CGX-L.
    they will track 20° past on either side, (so you can start imaging sooner.)
    They will both go 2 hrs past without a problem and both do have both hard and software config stops.
    One of the main reasons I bought mine.
