There are two things you can do to keep the noise down
1) You can set a maximum slew rate in the Hbx
This limits the slew rate to whatever you enter in degrees per second.
Thus your slewing to target may take a bit longer, but the motor noise dies dramatically at the lower rates, and the autostar alignment stays good.
2) If you are polar, you "may" be able to declutch without losing alignment, but "only" if you are polar.
I havent tried ( accuracy wise ) with large sky traverses, but the HBx has a synch function, which effectively reorientates the scopes idea of where it is pointing
If you were on one target, you could select yr new target via the Hbx but dont hit goto. This preloads the scopes target data to the new object.
Declutch and manually slew to new target. Use HBx to do a fine centre, then do a synch. This tells the system to set its idea of where the encoders are to match the new target.
That "should" work, but it relies on "you" getting the target ID correct, as you cant use the HBx readout to tell you where you are whilst doing this.
( You can use the manual setting circles in the normal manner to assist in doing the manual slew, that will get you very close )
