It is important to remember that temperature shifts will change the length of the optical path due to the differential contraction between the telescope tube and the glass optical elements. It is recommended that the photographers check focus either manually or automatically in software every 1 to 2 hours. In cases where the telescope has been brought from a warm environment to outside, more frequent focus checks are required until the equipment has stabilized nearer to ambient temperature. \u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBasic Substrate: optical substrate \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFilter Thickness: \u003c\/span\u003e\u003cspan\u003e2mm+\/-0.05mm for 2’’\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSurface Quality: S\/D (scratch\/dig)= 60\/40 (Refer to MIL-O-13830) \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTransmitted Wavefront: Lambda\/4 or better. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eParallelism: less than 30 arcsec \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSingle \/ Non-glued substrate\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWarranty: 3-years against delamination \u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFilter Ring: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e2\"(M48*0.75)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eUltra-thin filter cell to minimize vignetting \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBlack anodized finish Laser engraving \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNo fading\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eIn the box: \u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAntlia LRGB-V Pro series 2\" mounted set includes Luminance (IR\/UV-blocked colorless), Red, Green and Blue filters\u003c\/span\u003e\u003c\/p\u003e","brand":"Antlia","offers":[{"title":"Default Title","offer_id":43305716744305,"sku":"USED060307","price":469.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/20260603_152112.jpg?v=1780514709","url":"https:\/\/khanscope.com\/fr\/products\/antlia-lrgb-v-pro-filter-set-2-lrgb-v-pro-2-pre-owned","provider":"Khan Scope Centre","version":"1.0","type":"link"}
