Vespera II

The Vespera Dual Band Filter is a dual narrowband interference filter that will significantly improve your photo quality whether you are viewing from an urban or natural environment.

By selecting very precisely the wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III), found mainly in nebulae, the filter will increase the contrast between the Stellar object and the sky background. Thus, its use makes it possible to obtain a higher-quality image, with sharper stars and finer details.

Keep only the essential

The Dual Band filter has been designed to allow only two particular wavelengths to pass through to the Vespera sensor:
- O-III
- H-alpha

Due to the filtered wavelengths, it is particularly effective for photographing nebulae in emission (e.g.: Orion nebula M42, Heart nebula IC 1805 …), dark nebulae endowed with hydrogen (e.g.: Horsehead or Elephant's Trunk nebula...), planetary nebulae (e.g.: Owl nebula M97, Dumbbell nebula M27...), supernova remnants (e.g.: Veil nebula, Crab Nebula M1...).

For globular clusters (e.g.: Hercules cluster M13, cluster M92...), the selectivity of the Dual Band filter will help you to obtain sharper stars.

A filter specifically studied for Vespera

The optical quality of the Dual Band filter has been specifically studied by our engineers to offer use at full aperture, without any impact on the optical diameter of the instrument. The lens ring is equipped with an electronic micro-card that allows Vespera to detect the Dual Band filter and adapt its observation and image processing parameters.

Transmission curve

The filter features 12nm of bandwidth in each wavelength (O-III = 500.7nm, H-alpha = 656.3nm).

Astronomer by night, astronomer by day! Observe the closest star to Earth during the day with the Vespera solar filter. The filter allows you to observe sunspots (dark spots) that show the intensity of the Sun's activity.

Photograph the Sun with Vespera

The Solar Mode allows you to observe the Sun in almost real-time using the live display*. Capture photos at any time from the Observation tab of the Singularity mobile app.

Take several shots at different times of the day, week or month and compare your photos. Witness how the Sun's activity changes with the appearance or disappearance of sunspots. These can have a life span of several days, more rarely several weeks.

Sun spots monitoring

Automatic video recording for solar/planetary observation is not yet offered in Singularity. To make an animation, retrieve your photos in jpg format from Vespera's internal memory and put your photos together using photo/gif animation software.

*Continuous display of photos with a unit exposure time of 250µs

Observe safely

The filter is made of glass with a dimming effect. It will reduce the amount of light and allow you to observe the Sun in a way that is safe for your instrument. You will be guided through every step of your adventure by the Solar Mode of the Vaonis Singularity app, to ensure the observation runs smoothly and that you and your instrument are safe.

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.
