Much more important in pier design is to reduce vibration and ringing in the
mount. My design does still suffer from this when heavy vehicles go past the
house (the road is some 80 feet away). This can induce a wobble of up to ??
arcseconds which takes about 5 to 10 seconds to die away. In practice this
should not present too much of a problem since traffic is occasional during
observing sessions and only long exposure CCD images would be affected.
Following installation the pier was filled with sand to reduce vibration but I
never found much evidence that this actually helped!
The LX-200 is bolted to a 10mm stainless plate which fits over four mounting
bolts in a similar plate welded to the top of the pier. Lock nuts on the bolts
provide adjustment in two planes and allow for about 4 degrees latitude
adjustment - enough for any home I may own in the UK in the future!
