Skywatcher HEQ5 Pro knobs

[al-alami]

Hi All,

I find myself in a very weird place.  I seem to have misplaced the knobs that hold the vixen bar in place onto the puck.  Anyone have any idea where I can get them?  I tried using regular workshop screws, but the vixen bar keeps slipping.

Any help would be much appreciated.

Thanks in advance.

I would ring First light optics, always found Martin there to be most helpful.
