Solar Filter (AC021)
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 Pointing 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.
Sun spots observed on 12/07/2022 with the Vespera solar filter.
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.
- The Solar Pointing mode is not yet suitable for observing solar eclipses.
*Continuous display of photos with a unit exposure time of 250µs
Observe safely
The filter is made of a metalized foil 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 Pointing mode of the Vaonis Singularity app, to ensure the observation runs smoothly and that you and your instrument are safe.
Warnings
- Your Vespera station should never be pointed towards the sun unless a solar filter is installed.
- You can only use Vespera to observe the sun using the Solar Pointing feature of the Singularity app and the solar filter specially designed by Vaonis. The use of any other means to observe the Sun (pointing by coordinates, pointing by hand, use of any other filter, etc.) would void your warranty in the event of damage to your equipment. (see Warranties below).
- Never look directly at the sun without adequate protection. Direct observation of the sun without protection and without a solar filter, even for a short time, can lead to serious eye burns and potential loss of vision or even blindness.
- Do not attempt to open the lens ring that contains the filter (see Warranty below).
Dual Band Filter (AC022)
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).
Light Pollution Filter (AC023)
The Vespera light pollution filter or CLS (City Light Suppression) filter allows you to improve the quality of your photos when observing in the city or suburbs. It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky.
The broadband filter blocks Na (sodium) and Hg (mercury) wavelengths mainly emitted by urban night lighting or undesirable natural light (atmospheric oxygen radiation, etc.), while allowing the main wavelengths from celestial objects.
The anti-light pollution filter is particularly useful for improving the brightness of deep sky objects: nebulae, star clusters, galaxies, etc. It is especially effective on emission nebulae because of the filtered wavelengths.
Examples of emission nebulae: Bubble (NGC 7635), Crescent (NGC 6888), Eagle (M16), Elephant’s Trunk (IC 1396), Flame (NGC 2024), Lagoon (M8), North America (NGC 7000), Omega (M17), Orion (M42), Pacman (NGC 281), Rosette (NGC 2237), Tarantula (NGC 2070), Thor’s Helmet (NGC 2359), Trifid (M20), Tulip (Sh2-101).
Designed specifically for the Vespera lens, it fits easily and discreetly into the optical arm. The lens ring that holds the CLS filter is equipped with an electronic card that allows Vespera to detect it.
The filter is delivered in a transparent storage box.
