About this product
Model: vaonis_vespera_hygrometer
Part Number: AC024
In a cold or humid environment, dew can form on the lens of telescopes and cameras, affecting the quality of observation and photos.
The 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 station.
It is ideal for people living in a humid region (sea, ocean, river, lakes, ponds, etc.) or in a region where temperatures are cold. The sensor is also great in winter when temperatures are close to 0° Celsius.
Anti-fogging system
By equipping your station 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.
Improved focus
The condensation that produces fogging affects the focus of Vespera’s photo sensor:
Initialisation and acquisition times may be longer because a larger number of photos will be rejected by our image processing algorithms, which check the quality of the images and discard them if they are not of sufficient quality.
The sharpness of the pictures, which in astrophotography is mainly judged by the sharpness of the stars and the absence of any halo, is not as good.
The hygrometer and the associated demisting system will improve your observation and photos.
Discreet design
Measuring under 13mm, the hygrometer is equipped with an electronic board - the smallest board our expert engineers have ever designed. The sensor fits discreetly into Vespera’s optical arm, so it does not hinder the use of filters. It will automatically turn the anti-fog system on and off, so you never have to worry about it.

Installation can be tricky. I had to repeat installation of the device as initially it was not recognised. You have to really screw that thing in tightly to the point of almost stripping the threads. Once properly installed, the temp and humidity is shown on screen. I love it as I'm in a tropical country with high humidity and fogging can be a problem at nights.
