Kills my Celestron CGXL mount. Had to replace Celestron mount. Had to send the CGXL back to Celestron for repair. It was new. This CEM120 EC mount is awesome. Installed it on a Pier Tech pier. Only problem with it. When I turn it on. I get the main board error. Turn it off and back on. Then good to go. Tracking is dead on. Handles my 14" scope and other accessories no problem. Had to buy another weight for it. Came with two. I like the large screen on the hand control. So much better then the Celestron controller. I installed the QHY PoleMaster in it. Very easy install. Did the alignment. Tracking is dead on. Once I did the polar alignment. I keyed in the Ring Neblua. Bamm dead center. Polar alignment needs to be almost perfect for astrophotography. Have had no issues with elongated shots at two minutes or so exposure. I know this is not much of a review. This mount is well worth the money. I do have 4 or 5 dead pixels on the hand controller. Was like that as soon as I turned it on. Thought about contacting Ioptron about it. I would think they would replace it. Not sure if the EC or EC2 is worth the extra cost. As I start taking longer exposures I will find out.
Ioptron CEM 120EC
The mount arrived on time. Setting up the mount on the observatory pier went well. Then the fun started, The hand controller took numerous reboots to finally show something other than ...main board failure... Emails back and forth., That night the 2-3-4-5 minute exposures pictures centered around Capella were elongated... emails back and forth. Turns out there are 11 bolts that were only near hand tight. A calibrated torque wrench solved those issues, can’t believe the mount left quality control with that issue, we fixed it, with emails back and forth. The mount is now really nice. Ioptron support was helpful with solving the issues. A new HC is on its way, fit and finish is exceptional and we are looking forward to some unguided shots.
