  1. Hi. I'm looking for some advice. The NexStar+ hand controller on my Advanced VX mount just died. The light comes on for a second on the screen but then fades away. I am using an AC adapter to power the mount. The adapter is working. The small red light on the AVX stays on as usual. The problem seems confined to the HC. I am awaiting a reply from Celestron. There was no hints leading in to this that there was anything wrong. Do you think that it is repairable or do you think a replacement is called for? also, am I correct in thinking that the problem is confined to the HC? An AVX mount without a HC is a large piece of expensive metal. Thank you.
  2. Hi, can anybody help me. I’m trying to update my Celestron 8SE NexStar+ Handset Firmware using supplied RS-232 Lead connected via USB 232 Converter Lead, downloaded Celestron Firmware Manager and PL2303_Prolific_DriverInstaller_v10518. No joy, repeatedly Celestron Firmware Manager advises CFM was unable to find a device. Looking in Windows 10 Device Manager a new Port (COM & LPT) has appeared, (plug symbol covered with a yellow caution triangle) listing: Prolific USB-to-Serial Com Port (Com4) opened, general tab lists: This device cannot start (Code 10) A device which does not exist was specified. Any help would be appreciated, I’m going round in circles.
