Indeed! Thanks for the link and the good advice - the plug isn't even earthed!

Thanks Peter, that's useful info. Now all I have to do is find somewhere that sells a slow motion knob/cable that fits the shaft (5/16" is pretty close to 8mm). I've looked on Astroboot but it only seems to have the SW 6mm ones, even if they posted to the UK 😞 (although I do have relatives just over the border in Donegal). I'll be posting a wanted ad on astrobuysell and on cloudynights. Has anybody got suggestions for other possible sources, or know of any more modern mounts that have 8mm shafts instead of 6mm? I've confirmed that the motor is working and turning the worm shaft, and I can disengage relatively easily it by loosening the two bolts which hold it onto the mount frame 🙂

HI all, I've recently rediscovered a Fullerscopes 4" Newtonian reflector from my youth. Unfortunately, the telescope itself isn't in great shape (primary mirror seems to be corroded), but the mount seems to be usable (see attached photos). There is a motor drive on the RA axis, although I haven't checked yet to see if it still works, but I'd like be able to control the RA with a slow motion cable (or knob): - what do I need in order to add slow motion control to the RA axis (and maybe the Dec axis as well)? - where might I be able to source cables/knobs compatible with the Mk3 mount (I'm in the UK)? - do I need to disengage the motor drive in order to move the axis manually (with or without slow motion)? - is it worth thinking about a replacement mirror for the OTA, if so any recommendations? Any help/advice links appreciated, Thanks, Adrian ,
