This two-piece kit replaces the standard 1.25\" barrel entirely, threading directly onto the eyepiece's M45 threads to create a native 2\" nosepiece. The result is a more stable connection, eliminating wobble and ensuring perfect optical alignment within your 2\" diagonal or focuser.\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eDirect M45a Threading:\u003c\/strong\u003e Ensures a rigid, secure fit to the Hyperion Zoom MK III body, preventing any rotational play or sag.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eNative 2\" Format:\u003c\/strong\u003e Eliminates the need for a 1.25\"-to-2\" adapter, reducing the number of components in your optical train and the potential for misalignment.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eAccepts 2\" Filters:\u003c\/strong\u003e The nosepiece is threaded for standard M48 filters, allowing you to use your 2\" nebula or planetary filters directly with the Hyperion Zoom.\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWhy should I use this 2\" Nosepiece instead of a standard 1.25\"-to-2\" adapter with my Hyperion Zoom?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eThis Baader 2\" Nosepiece provides a more rigid, direct connection to the Hyperion Zoom MK III.
