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 wavelengths mainly emitted by urban night lighting or undesirable natural light, while allowing the main wavelengths from celestial objects.

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 wavelengths mainly emitted by urban night lighting or undesirable natural light, while allowing the main wavelengths from celestial objects.

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.

Transmission Curve

Additional information

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).

Description

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.

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.

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.

Learn more in the Vaonis blog article Observing the solar activity with Vespera.

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.
• 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

Benro Bracket for Binoculars

Made of lightweight and strong aluminium and treated with a scratch-resistant anodized finish, the Benro Arca-Swiss Style Binocular Bracket enables you to easily mount your binoculars outfitted with a 1/4"-20 threaded socket onto a photo/video/field tripod for hands-free use. Mounting your binoculars, especially high-powered sets or those with large objective lenses, onto a tripod or monopod helps to steady the view, reduce vibrations and eliminate arm fatigue.

The base of the adapter is designed to fit directly onto Arca-Swiss-style photo/video quick release heads, which eliminates the need for additional QR plates. If you aren't planning on using a head, or your head is not an Arca-Swiss-style, the base also has both 1/4"-20 and 3/8"-16 female threads that make it compatible with just about any quick release plate, head, photo/video/field tripod, monopod, or window mount available today.

The vertical upright on the adapter is triangular with a taper toward the top which helps it fit between the binoculars' optical tubes and giving you access to the minimum interpupillary adjustment even on larger-objective models. The wider base provides the strength and stability you need for heavier field binoculars. The upright also has two female 1/4"-20 threaded holes that you can use to keep the binoculars' mount hole cover safe or if objective caps are tethered to the mount cover you can still use them by installing them into one of the adapter's holes.

Since portability is so important factor as it is a lens that is often used for portraits with shallow depth of field,
we had to take the optical design, mechanism design, and electronics skills to the highest level in order to create a high-class telephoto prime lens.

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and TEC then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach TEC's expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

Produced in house, the Field Reducer Corrector, flattens the field of telescopic viewing and reduces the focal ratio by .9x: decreasing it from F/7 to F/6.3. Compared to a Field Flattener, the FRC will have small vignetting in the corners of FOW (~10%). Designed to cover an image circle ø 51mm, or 36x36mm, the FRC has a back focus extension of 115mm, making it perfect for deep space astro-photography.

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and we then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach Yuri’s expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

TEC Tube Rings are extremely lightweight and durable, with a set of two rings for an APO140FL F/7 weighing under 750g. The Tube Rings are CNC machined for clean edges with black anodized aluminum that is scratch resistant. They are outfitted with adjustable stainless-steel latches and are able to fit the TEC Dovetail Plates, Losmandy Plates, and AP Plates for secure mounting. Each Ring contains an upper base, an adjustable latch, and a lower base. The upper base of the Tube Rings also connects to the TEC Carry Handles for easy transport.
