De 279 mm opening vangt 1589 keer meer licht dan het blote oog: bolhopen tot in de kern, structuur in planetaire nevels en tijdens opposities oppervlaktedetail op Mars. De CGEM II draagt de 12,5 kg buis met ruime marge, ook met camera en toebehoren.<\/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\">De juiste montering voor elf inch<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op de lichtere Advanced VX werkt deze buis visueel prima, maar voor fotografie zit hij daar tegen de grens. De CGEM II lost dat op: stabiel volgen bij lange belichtingen en snel uitdempende trillingen bij het scherpstellen. Op papier is tot ongeveer 558x zinvol; de winst van elf inch zit in helderheid en resolutie bij elke vergroting die de lucht toelaat.<\/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>Optical tube SC 279\/2800 with 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<\/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>A <strong>moon filter (1.25 inch)<\/strong> dempt het felle maanlicht van deze grote opening.<\/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 279\/2800 CGEM II 1100<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>Optical design<\/strong><\/td><td>Schmidt-Cassegrain<\/td><\/tr><tr><td><strong>Opening<\/strong><\/td><td>279 mm (11 inches)<\/td><\/tr><tr><td><strong>Focal length<\/strong><\/td><td>2800 mm<\/td><\/tr><tr><td><strong>Opening ratio<\/strong><\/td><td>f\/10<\/td><\/tr><tr><td><strong>Maximum useful magnification<\/strong><\/td><td>558x<\/td><\/tr><tr><td><strong>Light output<\/strong><\/td><td>1589 times that of 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?
