First of all I 100% dispute the claims of @Zach540 - the LX850 is an excellent mount. I have owned two of them since 2013 and both have worked fantastic.
The first mount (until my home was robbed, grrrrr) was used 10 months of the year for about 5 years, about 150 nights/year. Not a single problem with the mount at all with this heavy use.
The second LX850 has been outdoors continuously along with the Eagle 2 computer from Prima Luce Labs. Mount is again used about 150 nights/year but this time has been outside continuously. To protect the telescope from the elements I use the Telegizmos 365 cover...this works fantastic. Mind you, even though the rig with cover experiences monsoon rain, snow, dust and a full spectrum of temperatures I am in New Mexico. For wetter climates I would look at JMI wheely bars or an observatory. This system can be setup easily it is just a huge rig.
My rig consists of the 14" f/8 ACF and Meade 80mm ED APO plus mounted Eagle and Cameras (Canon 60Da, Canon 80D, and the Meade DSI-IV). The LX850 handles the load without any troubles.
The mount works to the specs. It is VERY VERY easy to configure. With StarLock not only do you have the various easy align features, but also automatic drift align, auto PE Training and auto rate calibration. No need for external computers and added cables. The dual guiders and high precision pointing makes life a breeze. No need to fuss over the mount - you can focus on observing and imaging.
My typical routine once setup:
-- take off covers
-- power on all the components via the Eagle 2 (it does power management)
-- Go to a target around the celestial equator.
-- Do the Auto Rate Calibration (pushing 3 buttons?)
-- View, image and enjoy
-- When done auto park the telescope
-- Turn off the rig via the Eagle 2
-- Cover things up.
Again, contrary to the comments, covering 150 days/year and putting in about 10 hours/night on average with nary a problem I swear by the mount.
Oh, when I do have need to deal with Customer Service - no problem. Friendly folks!
