It blocks stray side light from reaching the primary mirror, improving contrast during both visual observing and imaging.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe design includes mounting holes for a standard 80×80 mm PC fan, mounted with screws. The fan helps prevent dew formation on the primary mirror and allows it to reach ambient temperature faster, resulting in more stable images.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI highly recommend using a fan with a dust cover or dust filter to prevent dust buildup and keep the primary mirror clean.\u003c\/p\u003e\u003cp\u003eThe part snaps on securely and holds firmly in place without the need for additional modifications.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThis model was printed in Sunlu PETG. I recommend PETG if the telescope is exposed to direct sunlight during the day, due to its higher temperature resistance compared to PLA.\u003c\/p\u003e\u003cboostme\u003e\u003cboosttitle\u003eBoost Me\u003c\/boosttitle\u003e\u003cboostcontent\u003eClear skies, sharp focus, no dew — boost if this print earns a place on your telescope 🔭\u003c\/boostcontent\u003e\u003c\/boostme\u003e\u003cp\u003eDesign by wyLam on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67398071943472,"sku":null,"price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_1fa1aec7-649d-431b-a4da-2a6e972e0947.png?v=1784877312","url":"https:\/\/mymadmanlab.com\/products\/skywatcher-200p-primary-mirror-light-blocker","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
