It offers the benefits of our revolutionary &ldquo;center balance&rdquo; design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 115 lbs (52 kg). The &ldquo;center balance&rdquo; design&rsquo;s natural stability is due to its focusing the mount along with payloads weight directly over the center of the pier or tripod. Along with the stability aspect, the CEM120 features an advanced cable management system consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured cables. They also add some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.&nbsp;<br /><br />The CEM120EC2 utilizes two high resolution encoders, one on each axis. The two encoders enable the mount to perform dual axes tracking. With advanced sky modeling the CEM120EC2 will be able to account and adjust for polar alignment error as well as changes in atmospheric (refractive) distortion. Fixed home sensors on each axis, allow the mount to save alignment models after power off too to be used on future nights.&nbsp;<br /><br />Optional heavy duty&nbsp;<a style="color: #0000ff;" href="http://www.ioptron.com/product-p/8037.htm"><strong>Tri-Pier 360</strong></a>&nbsp;and&nbsp;<a style="color: #0000ff;" href="http://www.ioptron.com/product-p/8038.htm"><strong>Permanent Pier</strong></a>&nbsp;are available for order.&nbsp;<br /><br />Optional Tri-Pier adapter for light weight payload (&nbsp;<a style="color: #0000ff;" href="http://www.ioptron.com/product-p/8036.htm">8036-120</a>) is also available for $129. It can be modified for permanent pier mounting.</span> <div>&nbsp;</div> <div>&nbsp;</div> </div> </td> </tr> </tbody> </table> </td> <td style="font-size: 13px;" valign="middle" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> </tr> </tbody> </table> <div id="ProductDetail_ProductDetails_div2" style="color: #585858;"> <table class="colors_descriptionbox" border="0" width="100%" cellspacing="0" cellpadding="0"> <tbody> <tr> <td style="font-size: 13px;" valign="bottom" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Left_Bottom.gif" alt="" /></td> <td style="font-size: 13px;" valign="top" width="100%"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" align="left" valign="bottom" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Right_Bottom.gif" alt="" /></td> </tr> <tr> <td style="font-size: 13px;" align="left" valign="top" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Left_MidDiv.gif" alt="" /></td> <td style="font-size: 13px;" valign="top" width="100%"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" align="left" valign="top" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Right_MidDiv.gif" alt="" /></td> </tr> <tr> <td style="font-size: 13px;" valign="middle" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" valign="top" width="100%"> <table border="0" width="100%" cellspacing="0" cellpadding="0"> <tbody> <tr> <td style="color: #585858;
