De 235 mm opening vangt 1127 keer meer licht dan het blote oog en het extra vergevingsgezinde optische ontwerp van de 9.25 staat bekend om zijn rustige, scherpe beeld. Op de CGEM II blijft dat beeld ook op de hoogste vergrotingen trillingsvrij.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">The CGEM II Mount: Room for Serious Photography<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The CGEM II is Celestron's heavier-duty German equatorial GoTo mount: 18 kg (40 lbs) payload capacity, NexStar+ hand controller with over 40,000 objects, All-Star Polar Alignment, permanently programmable periodic error correction (PPEC), and an autoguider port. Where the Advanced VX reaches its limit with these tube sizes, the CGEM II has plenty of margin: precisely what long, unattended exposures require. The mount operates on 12V; a power tank is the logical addition.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Visueel en fotografisch in balans<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op papier is tot ongeveer 470x zinvol; de Nederlandse atmosfeer begrenst planeetwerk meestal rond 300x, en precies daar excelleert deze optiek. Fotografisch draagt de montering buis, camera en guider met ruime marge. Dezelfde buis op de lichtere Advanced VX bespaart budget voor wie vooral visueel kijkt.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What's in the box?<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Optische buis SC 235\/2350 met StarBright XLT-coating<\/li>\n\n\n\n<li>CGEM II GoTo Mount with NexStar+ Hand Controller<\/li>\n\n\n\n<li>Steel tripod with accessory tray<\/li>\n\n\n\n<li>Eyepiece and diagonal mirror (1.25 inch)<\/li>\n\n\n\n<li>Seeker<\/li>\n\n\n\n<li>Counterweights<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Featured accessories<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>Celestron PowerTank Lithium LT<\/strong> The mount feeds all night in the field.<\/li>\n\n\n\n<li>The <strong>Armor padded backpack for C9.25 tubes<\/strong> uit de bestaande bundel beschermt de optiek onderweg.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Specification<\/strong><\/td><td><strong>Celestron SC 235\/2350 CGEM II 925<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>Optical design<\/strong><\/td><td>Schmidt-Cassegrain<\/td><\/tr><tr><td><strong>Opening<\/strong><\/td><td>235 mm (9.25 inches)<\/td><\/tr><tr><td><strong>Focal length<\/strong><\/td><td>2350 mm<\/td><\/tr><tr><td><strong>Opening ratio<\/strong><\/td><td>f\/10<\/td><\/tr><tr><td><strong>Maximum useful magnification<\/strong><\/td><td>470x<\/td><\/tr><tr><td><strong>Light output<\/strong><\/td><td>1127x magnification compared to the naked eye<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>CGEM II, German equatorial GoTo (18 kg payload capacity)<\/td><\/tr><tr><td><strong>Hand controller<\/strong><\/td><td>NexStar+ with 40,000+ objects<\/td><\/tr><tr><td><strong>Autoguider port<\/strong><\/td><td>Yes<\/td><\/tr><tr><td><strong>Nutrition<\/strong><\/td><td>12V external<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Still unsure about the right model?
