With 841 times more light than the naked eye and a 2032 mm focal length, you'll achieve sharp planetary detail, resolving globular clusters, and detailed planetary nebulae, with the stability long photo sessions demand.<\/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\">When would you choose the CGEM II over the Advanced VX?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The same C8 tube is also available on the lighter Advanced VX. Choose the CGEM II when astrophotography is the primary goal: the wide carrying capacity margin dampens wind and vibrations and maintains high focal accuracy during long exposures, even with the camera, guide, and accessories attached to the tube. Realistic visual planetary work is possible down to about 300x under Dutch conditions.<\/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 203\/2032 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 (1.25 inch)<\/li>\n\n\n\n<li>Seeker<\/li>\n\n\n\n<li>Counterweight<\/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> the bright moonlight reflects off this eight-inch optic.<\/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 203\/2032 CGEM II 800<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>Optical design<\/strong><\/td><td>Schmidt-Cassegrain<\/td><\/tr><tr><td><strong>Opening<\/strong><\/td><td>203 mm (8 inches)<\/td><\/tr><tr><td><strong>Focal length<\/strong><\/td><td>2032 mm<\/td><\/tr><tr><td><strong>Opening ratio<\/strong><\/td><td>f\/10<\/td><\/tr><tr><td><strong>Maximum useful magnification<\/strong><\/td><td>406x<\/td><\/tr><tr><td><strong>Light output<\/strong><\/td><td>841 times relative 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?
