It bend to light to a slightly steeper angle. This refraction effect makes the object appear higher in the sky than if the atmosphere wasn’t there. The degree of refraction depends to a small degree on various things. Like temperature, humidity, observers and height above sea level. It does increases strongly with decreasing altitude of the object. For example, the image of the sun at sunset can actually be elevated by over 0.5°, which is slightly more than one solar diameter.\u003c\/p\u003e\n\u003cp\u003eLike most optical media the refractive (bending) power of the atmosphere is actually dependent on the wavelength of light. This is called optical dispersion. Atmospheric dispersion corrector means that actually the degree of ‘lift’ that the refraction causes depends not only on the angle of the light, but also the colour of that light. Atmospheric dispersion spreads the light from any point source into a vertical spectrum of colours whose length increases the lower the object is in the sky.\u003c\/p\u003e\n\u003cp\u003eThe schematic below illustrates this dispersion effect as light enters the atmosphere and also the lifted elevation of the image. The lift is wavelength dependent and hence the image is separated into different colours. A planet exhibiting bad atmospheric dispersion effects will have a blue fringe on the top edge and a red fringe on the bottom edge.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eYou can read in much more detail in this excellent article by Martin Lewis: \u003ca href=\"http:\/\/skyinspector.co.uk\/atm-dispersion-corrector--adc\"\u003ehttp:\/\/skyinspector.co.uk\/atm-dispersion-corrector–adc\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePrism Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eH-K9L(Schott BK7)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePrism Surface Accuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eλ\/10@632.8nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePrism Deviation Angler\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAR Coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection Camera\/Eyepiece Side\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.25″ Holder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection Telescope Side\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.25″ Nosepiece\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eADC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eManuals \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/istronomyplus.com\/fr\/pages\/zwo-warranty?_pos=1\u0026amp;_psq=zwo+warranty\u0026amp;_ss=e\u0026amp;_v=1.0\" rel=\"noopener\" target=\"_blank\"\u003eZWO 2-Years Warranty\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/istronomyplus.com\/pages\/zwo-guides-and-manuals\" rel=\"noopener\" target=\"_blank\"\u003eZWO General Product \u0026amp; Software Manuals\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/ZWO-ADC-Quick-Guide.pdf?v=1670453576\" target=\"_blank\"\u003eZWO ADC Quick Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/ZWO-ADC-Manual.pdf?v=1670453569\" target=\"_blank\"\u003eZWO ADC Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/ZWO-How-to-Clean-the-Prism-of-the-ADC.pdf?v=1670453599\" target=\"_blank\"\u003eZWO How to Clean the Prism of the ADC\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/ZWO-Atmospheric-Dispersion-Corrector-ADC-Transmission-curve.pdf?v=1670453699\" target=\"_blank\"\u003eZWO Atmospheric Dispersion Corrector (ADC) Transmission curve\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/ZWO-Atmospheric-Dispersion-Corrector-ADC-Mechanical-Drawing.pdf?v=1670453694\" target=\"_blank\"\u003eZWO Atmospheric Dispersion Corrector (ADC) Mechanical Drawing\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"ZWO","offers":[{"title":"Default Title","offer_id":43133295067365,"sku":"ZWO-ADC","price":209.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/zwo-atmospheric-dispersion-corrector-adc-astronomy-plus_02e753a2-4772-4238-b7c4-fd2a13346044.jpg?v=1690484758"},{"product_id":"svbony-1-25-atmospheric-dispersion-corrector-w9157b","title":"SVBONY SV199 ADC 1.25\" Atmospheric Dispersion Corrector (W9157B)","description":"\u003ch1\u003eSVBONY SV199 ADC 1.25\" Atmospheric Dispersion Corrector\u003c\/h1\u003e\n\u003cdiv style=\"text-align: start;\" class=\"product-single__description rte\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFMC Prism Lens\u003c\/strong\u003e: The prism lens adopts double-sided coating technology to reduce light loss.
