In a cold or humid environment, droplets and fog can form on the lens of telescopes and cameras, affecting both the quality of observation and photos.\u003c\/p\u003e\n\u003cp\u003eThe Vespera hygrometer is an intelligent accessory that measures the temperature and humidity threshold of your environment at which fogging occurs on the lens of your location.\u003c\/p\u003e\n\u003cp\u003eIt is ideal for people living in humid regions such as near the sea, rivers or lakes etc. or in a region where temperatures are damp and cold. The sensor is also great in winter when temperatures are close to 0° Celsius.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnti-fogging system:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBy equipping your Telescope with this sensor, Vespera's integral demister will activate when a certain temperature and humidity threshold is reached. Heat generated continuously around the lens will remove the fog, creating better viewing conditions and sharper pictures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved focus:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe condensation that produces fogging affects the focus of Vespera's photo sensor.\u003c\/p\u003e\n\u003cp\u003eInitialization and acquisition times may be longer because a larger number of photos will be rejected by the telescopes image processing algorithms, which check the quality of the images and discard them if they are not of sufficient quality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA discreet design:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMeasuring under 13mm, the hygrometer is equipped with an electronic board which is the smallest board Vaonis engineers have ever designed. The sensor fits discreetly into Vespera’s optical arm and is compatible with the use of filters. It will automatically turn the anti-fog system on and off, so you never have to worry about it.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli style=\"font-style: italic;\"\u003e\u003cem\u003eVespera Hygrometer Sensor\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Vaonis","offers":[{"title":"Default Title","offer_id":56540400877903,"sku":"AC024","price":120.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/VesperaHygrometer_5.jpg?v=1764696260","url":"https:\/\/www.horizonastronomy.ie\/en-at\/products\/vespera-hygrometer-sensor","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
