Suitable sensors include KAF\/KAI, Sony, GSENSE and other sensor manufacturers. This filter set is designed to approximately equalize the RGB response from monochrome sensors . The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced dark frame library.\u003cbr\u003eThe LRGB V-series filters highlight both the spectral gap design between green and red filters to minimize effect of light pollution and high transmittance of useful emission lines which means it remains effective for weaker emission lines from galaxies and nebulae. The V-series filters guarantee the high transmission of the OIII band in both the B and G filters (OIII signal \u0026gt;95% in blue and green).\u003cbr\u003eThe bandwidth of the B channel is narrowed for the purpose of effectively improving the blue overflow around the star due to B channel overexposure when RGB is synthesized.\u003cbr\u003eThe Antlia V-series filters block the emission line around 589nm, which suppresses much of the light pollution from high pressure sodium and mercury street lamps and results in a more natural color balance. The uniformity in substrate thickness delivers good parfocal performance across all of its narrowband filters.\u003c\/p\u003e\n\u003ch3\u003eApplication and Performance:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for monochrome CCD and CMOS cameras;\u003c\/li\u003e\n\u003cli\u003eGreat imaging colors for celestial objects, galaxies, star clusters and nebulae;\u003c\/li\u003e\n\u003cli\u003eTransmittance rate＞95%, high optical throughput;\u003c\/li\u003e\n\u003cli\u003e2 sides AR coating, significant reflection and star halo reduction;\u003c\/li\u003e\n\u003cli\u003eRGB color combine 1:1:1, resulting in well balanced RGB and LRGB images;\u003c\/li\u003e\n\u003cli\u003eEqual RGB exposures means one master dark frame;\u003c\/li\u003e\n\u003cli\u003eParfocal across all filters in this set;\u003c\/li\u003e\n\u003cli\u003eImproved color separation with suppression of mercury and sodium lines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.365astronomy.com\/image\/cache\/wp\/ij\/content\/LRGB-V_Spectrum_Curve.webp\"\u003e\u003cimg src=\"https:\/\/www.365astronomy.com\/image\/cache\/wp\/ij\/content\/LRGB-V_Spectrum_Curve.webp\" alt=\"\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Data:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSchott optical substrate\u003c\/li\u003e\n\u003cli\u003e1.25”, 2” mounted, 31mm,36mm dia (2mm+\/-0.05mm)\u003c\/li\u003e\n\u003cli\u003e50mm dia，50*50mm，65*65mm square (3mm+\/-0.05mm)\u003c\/li\u003e\n\u003cli\u003eSurface Quality: 60\/40 (Refer to MIL-O-13830)\u003c\/li\u003e\n\u003cli\u003eBoth sides fine-optically polished to ensure accurate 1\/4 wavefront\u003c\/li\u003e\n\u003cli\u003e30 arcsec parallelism\u003c\/li\u003e\n\u003cli\u003eTave＞95%\u003c\/li\u003e\n\u003cli\u003eOD3（0.1%）@ 300-1050nm\u003c\/li\u003e\n\u003cli\u003eMulti-layer anti-reflection coating\u003c\/li\u003e\n\u003cli\u003eSingle Non-glued substrate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFilter Cell (specifications for cell mounted filters only):\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1.25” (M28.5*0.6)，2” (M48*0.75)\u003c\/li\u003e\n\u003cli\u003eUltra-thin filter cell to minimize vignetting by maximized possible clear aperture\u003c\/li\u003e\n\u003cli\u003eBlack Anodized Finish\u003c\/li\u003e\n\u003cli\u003eNon-Fading Laser Engraving\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSizes：\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMounted： 1.25” \u0026amp; 2” (2mm thickness)\u003c\/li\u003e\n\u003cli\u003eUnmounted：Dia 31mm，Dia 36mm (2mm thickness)\u003c\/li\u003e\n\u003cli\u003eUnmounted：Dia 50mm (3mm thickness)\u003c\/li\u003e\n\u003cli\u003eUnmounted：50*50*3mm，65*65*3mm square (3mm thickness)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\n\u003cbr\u003eNot recommended:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSolar Observing and imaging\u003c\/li\u003e\n\u003cli\u003eVisual observation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eIMPORTANT!\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eDO NOT LOOK AT THE SUN WITH ANTLIA FILTERS.\u003cbr\u003eSerious eye damage will result if you fail to observe the warning.\u003c\/p\u003e\n\u003ch3\u003eIn the box:\u003c\/h3\u003e\n\u003cp\u003eThis product listing is just for the L-filter, so it includes\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eone 2\" Luminance ( IR\/UV blocked colorless) filter\u003c\/strong\u003e\u003c\/p\u003e","brand":"Antlia","offers":[{"title":"Default Title","offer_id":49163812339971,"sku":"U2607-MS-ANTLIA-UV-IR-2","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/12e0cc36-3187-4abc-8b31-c17b04c5fba1_7b86a394-ccbc-49ae-bc02-d21b4ca326f3.jpg?v=1783122748","url":"https:\/\/milehighastro.com\/products\/used-antlia-l-filter-v-series-pro-uv-ir-cut-astronomy-imaging-filter-2","provider":"Mile High Astronomy","version":"1.0","type":"link"}
