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 EC version uses a high-resolution encoder to measure the actual movement of the right ascension axis and corrects the periodic error in real time to below 0.25 arcsecond RMS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With short and medium focal lengths, you photograph with it without autoguiding: less equipment, fewer cables, and a calmer workflow.<\/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-CEM70EC-Montering-iPolar-1.jpg\" alt=\"iOptron CEM70EC 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-CEM70EC-Montering-iPolar-2.jpg\" alt=\"iOptron CEM70EC 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-CEM70EC-Montering-iPolar-3.jpg\" alt=\"iOptron CEM70EC 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-CEM70EC-Montering-iPolar-4.jpg\" alt=\"iOptron CEM70EC 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-CEM70EC-Montering-iPolar-2.jpg\" alt=\"iOptron CEM70EC 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>Real-time error correction on the RA axis<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The encoder continuously corrects without PEC training or guiding camera.
