It features internal M48 female threads to accept filters or correctors and external M54 male threads to mount to focusers or other accessories, creating a secure, non-flexing connection.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eBridging M48 and M54 Thread Standards\u003c\/h3\u003e\n      \u003cp\u003eThis adapter solves a common problem: connecting an accessory with M48 threads, such as a 2\" filter or a field flattener, to a component that uses the larger M54 standard. The ring steps the thread size up from 48mm to 54mm. This version includes a physical lip, which acts as a hard stop when threading the adapter into a female port, ensuring it seats fully and squarely without being threaded too deeply.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWhat threads does the Starizona M48 to M54 Step Ring have?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eThe adapter has \u003cstrong\u003eM48 female threads\u003c\/strong\u003e on the inside and \u003cstrong\u003eM54 male threads\u003c\/strong\u003e on the outside.

You would typically thread your M48 accessory (like a filter cell or reducer with male threads) into the female side of this adapter. The entire assembly then presents a male M54 thread that can be connected to your focuser, camera rotator, or other M54-threaded accessory.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003ctable class=\"DAV-specifications\"\u003e\n    \u003ctbody\u003e\n      \u003ctr\u003e\n\u003ctd\u003eInner Thread\u003c\/td\u003e\n\u003ctd\u003eM48 Female\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOuter Thread\u003c\/td\u003e\n\u003ctd\u003eM54 Male\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n  \u003c\/table\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cul class=\"DAV-grid\"\u003e\n    \u003cli class=\"DAV-grid-item\"\u003e\n      \u003cdiv\u003e\n        \u003cp class=\"DAV-item-title\"\u003eStarizona M48 to M54 Step Ring with Lip\u003c\/p\u003e\n        \u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/starizona-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eStarizona Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Starizona","offers":[{"title":"Default Title","offer_id":68045007159581,"sku":"STZ-STEPL-M48-M54","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/Starizona-M48-to-M54-Step-Ring-with-Lip-1_b19c26ad-f7aa-4c0a-8d53-7ddf665a3890.jpg?v=1794410549","url":"https:\/\/davidastro.com\/en-int\/products\/starizona-m48-to-m54-step-ring-with-lip","provider":"David Astro","version":"1.0","type":"link"}
