The APO refractor is an absolutely upgraded version of the SV550 80mm. The refractor gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation, for galaxies, nebulae, star clusters and even some fainter deep sky objects, due to the higher limiting magnitude.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"product-single__title\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1050\/4506\/6060\/files\/6385784895283427625872940.jpg?v=1776249863\" alt=\"\"\u003e\u003c\/h2\u003e\n\u003ch2\u003e\n\u003cspan\u003eSV550 122 F7 APO Refractor Telescope for Deep Sky Astrophotography\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe OTA weighs only 6.44kg\/ 14.18lb, easy to carry out when fitting into the carrying case.
