Astroshop Maroc","og_description":"Omegon 200mm f\/3.2 Newtonian Astrograph  The compact and portable Newtonian Astrograph has been developed for the dedicated astrophotographer who wants a powerful telescope with very good sharpness over a large field of view. The Astrograph has been developed for modern sensors with high resolution and large diameters up to full format.  The extremely fast aperture ratio of f\/3.2 allows you to take very deep shots of deep-sky objects in just one night, while maintaining very high magnification. Images of extended nebula objects or galaxy clusters are thus possible.  &nbsp;  The highlights at a glance:   Parabolic primary mirror with a 200mm, f\/3.2 aperture  3\" corrector with 0.85 reduction built into the focuser  90mm diameter secondary mirror (minor axis) for full illumination up to full format  Large 3\" rack and pinion focuser with reduction and M48 adapter  Tilting possibility at the focuser  Adjustable and stable holder for primary mirror and secondary mirror  Fully illuminated and corrected image field of 44mm diameter  Working distance of 55mm from the M48x0.75 thread  &nbsp;  The mount head weighs only 8.2 kg, yet can support a payload of up to 18 kg. This extremly good\u00a0payload to weight ratio of 2.5\u00a0makes the CEM40 versatile. You can carry it to your favoriert place under a dark sky or at your backyard observatory with a relatively small pier.  But there are\u00a0more advantages:   An integrated\u00a0electronic polar finder scope\u00a0(iPolar) ensures accurate alignment even at times when the pole star is obscured.  Large levers\u00a0on its quick-lock drive engagement system make it easy to snap its gears into place even when wearing gloves.  There's little chance of your cables getting snagged with the CEM40's\u00a0internal cable management system.  The mount comes with the new\u00a0Universal Self-Centering Saddle\u00a0for Losmandy and Vixen style dovetails.  The CNC body looks sharp but is really robust.  &nbsp;  The\u00a0GoTo-Technology\u00a0features a Go2Nova 8407+ controller with integrated heater for its large display, a 212,000 object library, integrated\u00a032-channel-GPS\u00a0and ST-4 auto guiding port.  Another great feature besides the center-balance is the\u00a0ultra-quiet\u00a0low power consumption stepper motor drive systems. Both models of the CEM40 are precise trackers, the CEM40-EC version delivering &lt;0.25 arcsecond accuracy with its high-resolution encoder and its real time periodic error correction (RPEC).  The CEM40 is a extremly versatile and advanced mount.","og_url":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40","og_site_name":"Astroshop Maroc","article_modified_time":"2025-11-19T08:15:01+00:00","og_image":[{"width":800,"height":800,"url":"https:\/\/astroshop.ma\/wp-content\/uploads\/2022\/06\/Omegon-Telescope-Pro-Astrograph-N-200-640-OTA-CEM40.webp","type":"image\/webp"}],"twitter_card":"summary_large_image","twitter_misc":{"Est. reading time":"1 minute"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40","url":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40","name":"Omegon Telescope Pro Astrograph N 200\/640 OTA CEM40 - Astroshop Maroc","isPartOf":{"@id":"https:\/\/astroshop.ma\/#website"},"primaryImageOfPage":{"@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40#primaryimage"},"image":{"@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40#primaryimage"},"thumbnailUrl":"https:\/\/astroshop.ma\/wp-content\/uploads\/2022\/06\/Omegon-Telescope-Pro-Astrograph-N-200-640-OTA-CEM40.webp","datePublished":"2022-06-24T11:00:45+00:00","dateModified":"2025-11-19T08:15:01+00:00","breadcrumb":{"@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40"]}]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40#primaryimage","url":"https:\/\/astroshop.ma\/wp-content\/uploads\/2022\/06\/Omegon-Telescope-Pro-Astrograph-N-200-640-OTA-CEM40.webp","contentUrl":"https:\/\/astroshop.ma\/wp-content\/uploads\/2022\/06\/Omegon-Telescope-Pro-Astrograph-N-200-640-OTA-CEM40.webp","width":800,"height":800},{"@type":"BreadcrumbList","@id":"https:\/\/astroshop.ma\/?product=omegon-telescope-pro-astrograph-n-200-640-ota-cem40#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/astroshop.ma\/"},{"@type":"ListItem","position":2,"name":"Shop","item":"https:\/\/astroshop.ma\/?page_id=394"},{"@type":"ListItem","position":3,"name":"Omegon Telescope Pro Astrograph N 200\/640 OTA CEM40"}]},{"@type":"WebSite","@id":"https:\/\/astroshop.ma\/#website","url":"https:\/\/astroshop.ma\/","name":"Astroshop Maroc","description":"Des instruments astronomiques pour chaque astronome au Maroc","publisher":{"@id":"https:\/\/astroshop.ma\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/astroshop.ma\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"},{"@type":"Organization","@id":"https:\/\/astroshop.ma\/#organization","name":"Astroshop Maroc","url":"https:\/\/astroshop.ma\/","logo":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/astroshop.ma\/#\/schema\/logo\/image\/","url":"https:\/\/astroshop.ma\/wp-content\/uploads\/2025\/12\/M20_Logo_1.jpg","contentUrl":"https:\/\/astroshop.ma\/wp-content\/uploads\/2025\/12\/M20_Logo_1.jpg","width":501,"height":334,"caption":"Astroshop Maroc"},"image":{"@id":"https:\/\/astroshop.ma\/#\/schema\/logo\/image\/"}}]}},"_links":{"self":[{"href":"https:\/\/astroshop.ma\/index.php?rest_route=\/wp\/v2\/product\/8640","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/astroshop.ma\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/astroshop.ma\/index.php?rest_route=\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/astroshop.ma\/index.php?rest_route=\/wp\/v2\/media\/8641"}],"wp:attachment":[{"href":"https:\/\/astroshop.ma\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=8640"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/astroshop.ma\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=8640"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/astroshop.ma\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=8640"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/astroshop.ma\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=8640"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
