Its internal Petzval optical design provides a flat, well‑corrected imaging field optimized for APS‑C and 1″‑type sensors, so you get sharp, detailed images across the frame without the need for additional flatteners. With a fast f\/3.8 focal ratio and short 190 mm focal length, the 50P excels at capturing large nebulae, Milky Way fields, and deep‑sky targets with excellent efficiency and portability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/5292dcab-fa56-4457-8879-1512e5618129.jpg?v=1772303122\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/6813d778-e041-4259-a22d-18dbc475980c.jpg?v=1772303156\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/338d954a-38b6-4f25-b820-43c327bc4c1a.jpg?v=1772303189\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/0cfe59cc-1766-441b-af73-f2ea07d756c9.jpg?v=1772303205\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/907ef3e5-4a40-46a9-b000-c0c7cc97a559_1.jpg?v=1772303230\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/55ea76d3-0a16-4cc6-9f7b-ab8ddbf67162.jpg?v=1772303248\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"ck-table-resized\" align=\"center\" cellspacing=\"0\" border=\"0\" style=\"width: 99.9589%;
