It also helps block unwanted light entering\n    from outside the telescope’s field of view.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWhat is the Bahtinov focus mask used for?\u003c\/h3\u003e\n  \u003cp\u003e\n    The mask creates diffraction spikes around a bright star. When the\n    central spike is centred between the other two, it indicates good\n    focus. It provides a visual way to check focus and guide manual\n    adjustments.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eDo I leave the focus mask attached while imaging?\u003c\/h3\u003e\n  \u003cp\u003e\n    No. Remove the Bahtinov mask after checking focus and before capturing\n    your images. The dew shield remains in place during imaging.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWill the dew shield completely prevent condensation?\u003c\/h3\u003e\n  \u003cp\u003e\n    It helps delay dew formation, but condensation can still occur in\n    humid conditions. Active dew heating may still be needed.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eDoes this version fit the Seestar S30 or S30 Pro?\u003c\/h3\u003e\n  \u003cp\u003e\n    This version is designed for the ZWO Seestar S50. Choose the separate\n    S30 \/ S30 Pro dew shield for those models.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWhat is included?\u003c\/h3\u003e\n  \u003cp\u003e\n    One Starfield Optics dew shield and one removable Bahtinov focus mask.\n    Telescope not included.\n  \u003c\/p\u003e\n\n  \u003ch2\u003eProduct Finish\u003c\/h2\u003e\n  \u003cp\u003e\n    Visible print layers and minor surface variations are normal for\n    3D printed products.\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Starfield Optics","offers":[{"title":"Default Title","offer_id":49870196867143,"sku":"SFS50-Dew-02","price":29.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/1631\/6487\/files\/S50DewShieldandFocusmask-1.jpg?v=1792776571","url":"https:\/\/starfieldoptics.com\/products\/starfield-optics-dew-shield-for-zwo-seestar-s50","provider":"Starfield Optics","version":"1.0","type":"link"}
