    Got this to update the firmware on the telescope hand controller, works great! Review by Muris (Posted on 6/10/2017)
    Not suitable for Upgraded Celestron computerised hand controls with mini USB
    Overall Score
    I bought this cable (and the USB adapter) for my recently purchased celestron Nexstar 4SE, before I realised my hand controller had been upgraded to connect to the cable attached to the scope with a mini USB port. This cable is now redundant for the latest version of the Nextstar hand controller. A USB ---> mini USB cable was all I needed to control my 4SE via my computer. I'd advise to confirm what port you have on the bottom of the hand controller before purchasing. Review by JPC (Posted on 6/10/2017)
    Celestron NexStar RS-232 Cable works with Optex Serial RS-232 to USB Adapter
    Overall Score
    Bought the cable and Optex USB adapter to update firmware on my NexStar telescope hand control and use NexRemote software to control the telescope setup. Both the cable and adapter worked as expected after working around compatibility issues with Celestron's 'legacy' software running under Windows 10. Review by Gary (Posted on 6/10/2017)
    Item as expected, I need to get the SerialConverter for Laptop then I will know how well the cable works.
