For Vespera I, Vespera II & Vespera Passengers only
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 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:

• Initialization 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 both your observation and your photos.

A discreet design

Measuring under 13mm, the hygrometer is equipped with an electronic board which is the smallest board our expert 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.

Take your Vespera wherever you go with this specially designed backpack to safely carry your observation station.

Take Vespera with you wherever you go
Weighing only 1 kg, the bag makes it easy to carry Vespera when traveling or enjoying an evening under the stars. It's small enough to fit easily in the car or on public transport. It can also be transformed into a hiking or leisure bag by simply removing the removable interior compartment.

Protect your station
The backpack is made of a soft material that is resistant to rain, dust and wear. The Vespera's shell is protected from impacts and scratches thanks to the foam padding over the entire surface of the bag and a fully padded interior. The compartments and numerous pockets prevent the accessories from rubbing against the observation station.

Storage space for all your accessories
The Vespera backpack designed by Vaonis offers a host of storage spaces for your observation station and its accessories: tripod, charger, filters, tablet, cell phone, back up battery, etc.

Unparalleled comfort for carrying a telescope
The back panel is reinforced to provide greater comfort when carrying the bag. The shoulder straps are padded and lined with mesh fabric for improved ventilation when wearing the bag on your back for long periods of time or in high temperatures.
