Quite right Fred - I only allow DEC correction in one direction to avoid backlash issues (does not seem to have worked this time!). My SXW has fairly large backlash on DEC if I correct at siderial type rates, eg 10s for a reversal. Correcting DEC cin both directions usually makes things worse. BTW is it normal practice to correct DEC slowly? I know RA corrections are kept below siderial to avoaid unloading the gears but what is best practice for DEC ? I use 0.5 for RA and 0.8 for DEC but really have no reason for the DEC selection?
