The weight is centered directly above the center of the tripod or column, which gives this mid-range mount its characteristic stability and tracking accuracy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ECW combines the real-time RA encoder with built-in WLAN: encoder accuracy without autoguiding, operated wirelessly from your laptop, tablet or phone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the built-in iPolar, GPS and internal cable management, this is a complete precision head for the demanding photographer.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-1.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-3.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-2.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-4.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n<\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-3.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\"><strong>Wireless and without guiding<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The encoder corrects the periodic error in real time to less than 0.25 arcsecond RMS; the WLAN connects the mount to SkySafari, iOptron Commander or ASCOM without a cable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For long focal point-to-point distances, ST-4 auto guidance remains available.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/iOptron-CEM70-ECW-Montering-iPolar-2.jpg\" alt=\"iOptron CEM70 ECW Mount iPolar\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\"><strong>GoTo with GPS and heated hand controls<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Go2Nova 8407+ hand controller contains over 200,000 objects and has a display heater for cold nights.
