Just bought a new S.W. CQ350 mount and the Dec backlash is 0.5mm at the end of the saddle! Does anyone know how to adjust the Dec backlash on these mounts. Thanks
Sky Watcher CQ350 backlash issues
Lil bit late but maybe it helps someone. You got the first version or the 2nd one? There is a german PDF https://www.teleskop-express.de/media/pdf/CQ350-Einstellen-Schneckenspiel.pdf
The first version of this mount do not have these 4 screwes and the backlash can not be adjusted from outside. You need to open the whole mont and do the same thing like in the PDF.
