Skywatcher auto focuser screw size ?

Recommended Posts

Hi All

I have this auto focuser to fit but no screws ! Just wondering if anyone can tell me the correct screw size for the 4 screws that normally come with this auto focuser kit please ? I mean the small screws that bolt the bracket to the focuser and telescope body. There are 4 of them and they are longer than the standard screws to accommodate the bracket.

Thinking I’ll to try to source some from ebay if possible.

I have precisely the same question! Please consider this thread bumped. Can anyone help? I'm transplanting an auto focuser from a 130P to a PDS and I need the longer screws (actually they're allen/hex head screws) to fit through the bracket, through the focuser plate, and into the focuser body.

The longer screws supplied with the SW focus motor are M3 x 12.



Brilliant - thank you (sorry it took a while to see & respond)
