Ontworpen voor observatoria en vaste opstellingen met grote optiek en complete fotosystemen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De EC-uitvoering meet de rechteklimmingsas met een hoge-resolutie encoder en corrigeert de periodieke fout in realtime. Voor veel fotosetups vervalt daarmee de autoguiding op de RA-as.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Alle observatoriumfuncties van de CEM120 blijven aan boord: GPS, WiFi, LAN en het uitgebreide kabelmanagement.<\/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-CEM120EC-Montering-GoTo-High-Precision-Encoder-3.jpg\" alt=\"iOptron CEM120EC Mount GoTo High Precision Encoder\" title=\"\"><\/figure>\n<\/figure>\n\n\n\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\">De encoder stuurt continu bij zonder PEC-training. Sterren blijven strak in lange belichtingen, ook onbewaakt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Voor de declinatie-as en lange brandpuntsafstanden blijft ST-4 autoguiding beschikbaar.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Zwaar mechaniek, fijn volggedrag<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Assen van 80 mm dik draaien op lagers van 125 mm; de wormwielen van 216 mm met 360 tanden en een wormperiode van 240 seconden geven een volggedrag met een periodieke fout onder plus of min 3,5 boogseconden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Het veerbelaste Losmandy-zadel en de verstelbare contragewichtstang (bruikbaar tot op de evenaar) maken de montering geschikt voor vrijwel elke grote buis. De kop wordt zonder statief geleverd; de Tri-Pier met adapter of een vaste zuil is de passende basis.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Observatoriumklasse besturing<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">De Go2Nova 8407 V2 handbediening met displayverwarming bevat ruim 200.000 objecten. GPS, WiFi en een LAN-aansluiting zijn ingebouwd, zodat de montering direct in elk observatoriumnetwerk past.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Autoguiding kan via de ST-4-poort; het uitgebreide kabelmanagement met meerdere poorten houdt ook dubbele fotosetups opgeruimd.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Included<\/strong><\/h3>\n\n\n\n<ul
