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).

Additional information

Dew is one of the many enemies of amateur astronomers. In a cold or humid environment, droplets and dew can form on the lens of telescopes and cameras, affecting both the quality of observation and photos.

Vespera’s anti-dew system 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.

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-dew 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 dew, creating better viewing conditions and sharper pictures.

Improved focus

The condensation that produces dew or 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.

Instructions for installation

The box comes with:

• the hygrometer and a screw ready to be fitted,
• a mini screwdriver.

Remove the standard Vespera lens ring and carefully insert the hygrometer into the notch above the lens. Screw the sensor in tightly using the screwdriver provided in the box. The sensor must not move in its housing.

To verify that the sensor is properly positioned, connect Vespera to your mobile device and launch the Singularity app. In the Space Center and then the Instrument screen, the ambient temperature and humidity are displayed.

Directions for use:

• Make sure Vespera is turned off before installing or removing the hygrometer.
• You do not need to remove the sensor on each use. We recommended leaving it in your Vespera to avoid any loss or damage.
• Activating the demisting system results in higher battery consumption. We recommend you charge your station before using it.

Dew also occurs during large temperature changes, for example in winter, when you move from a warm to a cold environment and the air inside your Vespera has remained warm. We therefore recommend that you take your Vespera outside for at least 30 minutes before starting any observations so that it can adjust to the ambient temperature.

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.

Highlights:

• Ideal for visual observation and astrophotography.
• Designed for the amateur astronomer or photographer who wants to view and photograph the moon, planets, and deep sky objects.
• Features FPL53 "super" extra-low dispersion (ED) glass in a fully multicoated apochromatic lens system that corrects for both spherical and chromatic aberrations, astigmatism, and off-axis comas.
• This correction creates a wide flat field of view without distortion and removes the blue-tinted halo effect for true high-contrast color transmission.
• Can accept both 2" and 1.25" eyepieces and accessories for visual use.
• Threads on the drawtube allow direct connection of T-rings and other camera mounts.

A ring spacer placed around the objective lens refines star images beautifully in astrophotography.

In the previous SD81S model, a set of three tiny tin foils are placed around the objective lens as a spacer between the doublet lens. The end of the tin foils protruding over the objective lens obstruct the incoming light. As a result, the protruding tin foils make the light of diffraction of stars chipped radially. Exchanging the tin foils for the spacer ring makes the diffraction of the stars' light equal. It allows you to create more refined and beautiful star images in your astrophotography.

The SD lens suppresses residual chromatic aberration far below the threshold of visibility.

A lens of refracting telescopes has chromatic aberration which is caused by different wavelength of visible light (colors) focusing at different distances. The Vixen SD lenses, made of FPL53 super extra-low dispersion glass, allow for correcting the chromatic aberration over a wide spectrum of light. The SD81SII delivers outstandingly sharp images with high contrast for both visual and photographic applications. Moderately bright F7.7 images will satisfy the most demanding visual astronomer or astrophotographer.

A short optical tube in length is handy for not only visual observation but also astrophotography.

The ED81SII optical tube has a moderate short length to enable you to carry and set it up readily. Also, a lightweight optical tube allows you to balance it with fewer counterweights. The ED81S comes equipped with a metal carry handle and the Vixen standard dovetail slide bar M for quick attaching and detaching. The provided Flip mirror diagonal switches incoming light to allow for using two eyepieces of different magnifications alternately. Also, you can install a camera on the straight side and view an image through an eyepiece on the right-angled side of the flip mirror diagonal.

Full-frame imaging with a DSLR camera.

Using an SD reducer HD kit or an SD Flattener SD kit, which are available optionally, the SD80SII provides an image circle of 44mm, adequate for taking photos with a DSLR camera.

SD Reducer HD Kit: This kit includes a flattener lens to be combined with a reducer lens for a flat and wide imaging field when you use them with the SD81SII, SD103SII, or SD115SII optical tube. The reducer lens reduces a focal length by 0.7X. Direct Wide Photo Adapter 60DX: It is available for Canon EOS or Nikon DSLR cameras. It is possible to change the orientation of a camera for a framing of the photographic field.

Wide Photo Adapter 60DX

High precision camera adapters for prime focus astrophotography are optionally available for Canon EOS and Nikon. The Wide Photo Adapter 60DX is designed to be an integrated camera mount reducing vignetting to the maximum. They are highly effective with full-frame DSLR cameras, and can be used with SD series refractors (in combination with the SD Reducer HD Kit or SD Flattener HD Kit).
