By blocking invisible ultraviolet and infrared light, this 2-inch filter ensures your sensor only records the visible spectrum, resulting in sharper stars and truer colors. Designed with standard 2-inch filter threads, it installs directly onto 2-inch eyepieces, nosepieces, and filter wheels for immediate image improvement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSharpen Your Images: The 2-inch UV\/IR Cut Advantage\u003c\/h3\u003e\n\u003cp\u003eMany telescopes, particularly refractors, are not fully corrected for wavelengths outside the visible spectrum. When unfocused UV and IR light hits your sensor, it creates a soft halo around stars, reduces contrast, and can cause a magenta cast in your images. This 2-inch filter eliminates that problem by acting as a \"luminance\" filter for your one-shot-color camera, transmitting only visible light for tighter, higher-contrast results.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Critical L-Filter for 2-inch Color Imaging Setups\u003c\/h3\u003e\n\u003cp\u003eFor anyone using a modified DSLR, a dedicated astronomy CCD, or even a sensitive webcam for planetary imaging, this filter is not optional—it's necessary. Digital sensors have a native sensitivity to infrared light that the human eye lacks. This filter restores natural color balance, provides finer color gradation, and prevents the ghosting and internal reflections caused by IR radiation bouncing within the optical train.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eProtect Your Sensor with This 2-inch Optical Glass Filter\u003c\/h3\u003e\n\u003cp\u003eBeyond its optical benefits, this 2-inch UV\/IR Cut filter serves as a permanent, high-quality protector for your expensive camera sensor. Made from true optical quality glass, it shields the sensor from dust, moisture, and potential scratches without degrading image quality. It's an inexpensive insurance policy that keeps your primary imaging equipment safe while you work.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main purpose of this 2-inch UV\/IR Cut Filter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eIts primary job is to block invisible ultraviolet (UV) and infrared (IR) light from reaching your camera sensor. This is crucial because digital sensors are sensitive to these wavelengths, which can cause bloated stars, reduced contrast, and unnatural color casts in your astrophotos. It effectively cleans up the signal for a sharper, more accurate image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDo I need this 2-inch UV\/IR Cut filter for my modified DSLR camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003e\u003cstrong\u003eYes, absolutely.\u003c\/strong\u003e When a DSLR is \"astro-modified,\" the stock IR-blocking filter is removed to increase sensitivity to hydrogen-alpha light. A side effect is that the sensor becomes highly sensitive to all IR light, which will ruin color balance and sharpness. This external 2-inch filter restores the necessary IR cut, allowing you to capture nebulae while maintaining correct star colors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the 2-inch UV\/IR Cut Filter help when imaging with a refractor telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eRefractor telescopes, especially achromatic and some ED doublets, focus different colors of light at slightly different points. This effect, known as chromatic aberration, is often worse in the UV and IR spectrum. By blocking these wavelengths, the 2-inch filter prevents the \"blue-violet bloat\" and soft focus associated with unfocused light, leading to a much sharper final image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use this 2-inch filter for visual observing?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWhile it is optically transparent in the visible spectrum, a UV\/IR cut filter typically provides no noticeable benefit for visual observing. The human eye is not sensitive to the wavelengths it blocks. Its primary application is for imaging with digital sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill this 2-inch UV\/IR Cut Filter thread into my 2-inch eyepiece?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. This filter uses standard 2-inch filter threads (M48x0.75), which is the industry standard for 2-inch eyepieces, nosepieces, filter wheels, and other astronomy accessories. It should be compatible with any standard 2-inch format equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow will this 2-inch filter affect imaging the Orion Nebula (M42) with my color camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eUsing this 2-inch filter when imaging the Orion Nebula (M42) will result in a significantly better image. It will produce tighter, more defined stars in the Trapezium cluster, better contrast between the glowing gas and dark dust lanes, and more natural color rendition in the faint outer loops. Without it, the bright core can easily appear bloated and lose detail due to IR signal.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThis product is covered by a standard manufacturer's warranty.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SVBONY","offers":[{"title":"1.25\" Round Mounted","offer_id":52861233398045,"sku":"SV-F9127A","price":22.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round Mounted","offer_id":52861233430813,"sku":"SV-F9127B","price":25.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/SVBONY-2inch-UV-IR-Cut-Filter-1_12f74808-11aa-4745-b413-c46227b1a7b9.jpg?v=1788660020","url":"https:\/\/davidastro.com\/products\/svbony-uv-ir-cut-filter","provider":"David Astro","version":"1.0","type":"link"}
