The mask creates a distinctive diffraction-spike pattern; as you adjust focus, the central spike moves through the X formed by the others. When the central spike is perfectly centered and symmetrical, you are in sharp focus. Remove the mask slide and image as you normally would.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the Kit\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Mask Holder (custom-fit to the ZWO Seestar S50)\u003c\/li\u003e\n  \u003cli\u003e1 × Bahtinov Mask Slide for focusing\u003c\/li\u003e\n  \u003cli\u003e3 × Diffraction Spike Masks — 4-point, 6-point, and 8-point patterns for adding an aesthetic spike look to bright stars in your images\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAlways remove the Bahtinov Mask Pro holder before powering down your telescope.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt to Last\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVirtually indestructible ABS plastic\u003c\/strong\u003e — the same material used across the Farpoint mask line\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCustom-fit to the Seestar S50\u003c\/strong\u003e — no adapters, no guesswork\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemovable, reusable\u003c\/strong\u003e — focus, swap, or remove in seconds\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eProudly made in the USA\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eExplore the Full Mask Range\u003c\/h3\u003e\n\u003cp\u003eLooking for a mask for a different scope?
