Its 480mm focal length gives wide, bright views of nebulae, star clusters and the Moon. The optical design pairs an ED doublet objective with an integrated field-flattening element. This keeps chromatic aberration and field curvature under control and keeps stars sharp toward the edge of the frame, with no separate flattener to add to your imaging train.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/7_20261008152942_1818.webp?v=1792857808\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eMulti-layer anti-reflective coatings improve light transmission. Blackened lens edges and a matte-black interior suppress stray light, which helps contrast under light-polluted skies. The 2.5-inch rack-and-pinion focuser has a 10:1 fine-focus ratio and 60mm of travel. It has adjustable tension and a focus lock to prevent focus shift during long exposures. Pre-drilled holes let you add an electronic autofocuser (EAF) later, and an M63-to-M48 adapter is included for connecting cameras. The aluminum tube and multi-point metal tube ring complete the package.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTech Specs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
