Shipped on a pallet covered in crate.  The pictured pier is included.  Covers are 1/4" thick black textured ABS plastic. Black spray paint for plastic will cover most scratches !  Counterweights are included. 12" worm gear on the R.A. and a 8" worm gear on the Dec. axis Weight capacity is over 125 lbs., tested. Optics and mountings included in the weight capacity, not the counterweights. Electronics are a Sidereal technology servo controller and motors. The controller is on the R.A. cover. Should the electronics fail, user replacement is quick and simple. No need to send the mount somewhere ! Operated on 12-24 volts DC.  Software is FREE, updates are FREE ASCOM compliant.  XP compliant software. Autoguiding works well with a Meade DSI Pro and Ph.D. software.  All standard functions of typical GoTo mounts are included in the software, and MORE.  Will work with easily GoTo My PC remotely. Point and click GoTo's with most planetariums. Sky Charts, FREE, works fine.   Further information about the controller is also available on this page. A wireless handpad is available.  Wireless control from a laptop is available via a bluetooth serial connector.  Periodic Error This mount was tested and has a P.E. of approximately 5 arc seconds per worm revolution.  Typical PEC can be used in the software in addition to autoguiding if you are wanting to do CCD work.     Point XP Screen Shot This is part of the reason for the accuracy using this servo controller. After an offset initialization, ( point and click on a star) you start adding in "cal stars".  These are just plain stars that are centered on the CCD chip if you are imaging or in the eyepiece is you are doing a visual only session.  After about 5 of them, accuracy is such that polar alignment drift is nearly canceled out,  mount fabrication errors are compensated for etc.  Pointing accuracy will put a star near center of a CCD chip. The better the separation of the cal stars, the better the accuracy.  This is all done automatically. You need not even look at the PxP screen, just click on the button from the main screen when the star is centered. The recommended number of cal stars for the very best accuracy over the entire sky is 18. Accuracy is dramatically improved after 5 however.  With these cal stars, Polar alignment does not have to be "perfect" anymore. Some of the polar alignment routines in other programs are rather lengthy and time consuming. With PxP, that can be eliminated. Each axis will be used when tracking.    Manual A few users of this servo controller have made a manual. With the manual, there are also other users who have posted pictures and comments about the controller and software.    http://www.sitechservo.info/
