Vespera Hygrometer Sensor

Designed for Vespera I & Vespera II.

Fog is one of the many enemies of amateur astronomers. 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.

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 location.

It 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.

Anti-fogging system:

By 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.

Improved focus:

The condensation that produces fogging affects the focus of Vespera’s photo sensor.

Initialization 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.

A discreet design:

Measuring 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.
