Vixen’s latest design of polar finder, allows a simple, hassle-free method of polar alignment. The Vixen Polarscope PF-L II for AP & SX mounts has a reticule showing the Pole star (Polaris) and two other stars (Delta UMi and 51 Cep) in their precise positions. By turning the Polarscope you can easily match the reticle with the asterism of these stars in the sky and mechanically adjust your mount’s azimuth and altitude axes to align to the true North Pole. You can then adjust the Polar star to a more precise alignment using the reticule’s year marking (which runs from 2015 to 2040, but in practise can be used much longer after this) .
Using this alignment process, with visual reference to the actual stars in the sky, a complicated alignment, using date and time to calculate Polaris offset from the pole is unnecessary. For alignment in the Southern Hemisphere you simply use the Trapezium asterism (Sigma, Chi, Tau and Upsilon Octantis) of the constellation Octans and position the reticule with the trapezium stars aligned to their marked positions.
The Polarscope has built-in LED illumination, which is dimmable in many stages, and ensures an automatic shut-off after 2 minutes, saving your battery life.
The PFL-II also has an improved edge sharpness, when compared with its predecessor.

Fast 90 mm high-performance astrograph for demanding astrophotographers and observers with 5 lens elements in 5 groups. Due to the complex optical structure with five lens groups and five elements (quintuplet), including two SD (Super ED) lenses and an ED lens (Extra-low Dispersion) , a virtually aberration-free optical system was created.
This revolutionary astrograph is compatible with a full-frame digital DSLR or an even larger 44x33 mm camera. The 90 mm astrograph with fast aperture ratio delivers exceptionally sharp, high-contrast and small point stars from the centre to the corners of the field of view. In addition, it is also ideal for visual observation with a very large field of view but also for planetary observation with high magnification.
The VSD90ss is designed so that there is a "long peak range" in the adjustment accuracy of the sharpness, so that photographers can always achieve satisfactory results in astrophotography. Even if the focus is not quite precise, round and sharp stars are still shown throughout the entire image field.
Illumination without vignetting
In most cases, an astrograph also produces optical vignetting (a gradual decrease in light rays towards the edge of the image) This is mainly caused by rear lenses being shaded by the front lenses. Because of this darkening, it is relatively normal for the photographer to have to further edit the image after taking the picture and also have to do some additional so-called flats before taking the picture. To solve this problem, the VSD90ss uses wide aperture lenses in the rear elements, securing over 90 % of the light volume at the edge of the 60 mm image circle. Since the light intensity is uniform throughout the entire image field of the VSD90ss, there is no need for complex technology to prevent edge darkening. The VSD90ss is coated with the most modern coatings of extremely high reflectivity. These coatings have been specifically developed to optimize the properties of each individual lens element without degrading contrast and light intensity across multiple lenses.
Numerous gradations of light bring beautiful point-like stars into the image field
The low optical vignetting ensures sufficient illumination and thus eliminates the asymmetric flare caused by bright, diffraction-limited stars. It prevents stars at the edge of the 60 mm image circle from exhibiting deformations such as comets, astigmatism or coma. Since the illumination of the image field is relatively similar from the center to the edge of the image, you can expect excellent star imaging.
Please note:
*Depending on the recording system used, mechanical vignetting can still occur due to the camera body or incorrect adapters.
96.7% Strehl for impressive visual observations
The VSD90ss offers a flattened large field of view with a low magnification wide angle eyepiece. Even with a high-quality wide-field eyepiece with a large field of view, you can get sharp images of stars in the entire field of view when visually observing! In the centre of the field of view, a Strehl intensity of an impressive 96.7% is achieved at visible wavelengths. This Strehl ratio exceeds that of the SD81SII apochromat at 95.7%, which is known for its excellent optical properties, and this also works excellently when observing the moon and planets at high magnification.
The versatile large and stable focuser
The VSD90ss has a large focuser with a diameter of 87.5 mm to make optimal use of the large illumination field of 60 mm. With the large extension that is compatible with many accessories, it is perfect for astrophotography up to large format or 35 mm full frame DSLR cameras. Thanks to its precise manufacturing, it is also suitable for very heavy cameras without tipping.
The precision locking lever of the eyepiece extension
The focuser's extension tube has a locking lever that holds the extension tube firmly in position even when using heavy cameras such as large format cameras or CCD cameras with a large sensor. The locking lever clamps the rack gear to the extension barrel so that the viewing angle or focus on your camera does not shift.
Compatible with motor driven focusers
An optional two-speed motor focuser (not included) is available for the VSD90ss to provide sensitive focusing. An EAF (Electronic Automatic Focuser) from ZWO or equivalent can also be retrofitted.
Optional VSD Reducer for even faster results
The tried and tested optional VSD reducer, which was also used on the predecessor, the VSD 100, is also compatible with the VSD90ss. The photographer gets even faster results in astrophotography with an aperture ratio of 1:3.9.

In contrast to usual light, polarized light has a preferred vibration plane of the light waves. Polarized light lets be seen anisotropic objects, whose observable properties are depending on the direction, "in a new light": crystals, but also animal hairs, feathers, muscles, nerve fibres and vegetable cell walls, which have a preferred direction of its biomolecules, show structures now, which were hidden in the normal bright field image. Images made by polarized light are often characterized by a fantastic coloring. Polarization microscopes are used particularly in mineralogy, geology, biology and medicine.
In order to change the object's direction in a controlled way, the Science MPO 401 has a round, center-adjustable and full rotatable object stage with degree scale. The illumination and observation unit encloses e. g. the halogen bulb lamp (20 W) with dimmer, the field diaphragm (used to achieve the Köhler illumination), the 360° rotatable polarizer (for the production of polarized light), centering implements for the objectives and the analyzer attachment (for the analysis of the polarized light). The analyzer attachment is meant for receiving the 360° rotatable analyzer and optional available sliders (Bertrand lens for conoscopy; quartz wedge, lambda plate and lambda/4 plate used in order to get special colour effects). The wide field eyepieces (WF10x), which are also optional available, are placed at the trinocular head with an inclination of 30°. They have eye relief adjustment as well as diopter adjustment. The images shown by them are bright, true colored, sharp and rich in details. Apart from the slips and eyepieces, which were mentioned above, the accessories of the MPO 401 contain a dividing eyepiece (WF10x), the Abbe condenser with iris diaphragm, special polarization objectives (4x, 10x, 40x retractable, 100x-oil retractable), filters (blue, ground glass) and immersion oil.

The new BRESSER Nebula 5 EQ/AZ Wifi-Network Mount is a precise and quiet telescope mount – ideal for astrophotography. The controller box offers numerous central connectivity options for various accessories such as cameras, filter wheels, and motor focusers via USB (2.0/3.0), simplifying the setup of a professional astrophotography machine.
BRESSER has relied on innovation coupled with quality Made in Italy for this top-notch product. The manufacturer's long experience in mount construction guarantees a high-end device with first-class functionality and utmost reliability. Additionally, the in-house development team in Italy ensures quick response times in technical support and the adaptation of new device drivers. Truly, "Professionals at work!"
The mount is controlled via pre-installed web-app software, accessible via WIFI and Ethernet cable connection. The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a standard PC, which can be remotely controlled via a smart device such as a mobile phone or tablet. However, this does not exclude the traditional use of computers of all types and brands, which can be connected to the system either wired or wirelessly.
The BRESSER Nebula GoTo System Controller is a Raspberry Pi 4 microcomputer, which allows complete control of the setup (mount, camera, etc...) without the need for any other external device. The BRESSER Nebula GoTo system comes equipped with all Linux-based applications required for performing all astrophotographic functions.The existing INDI environment allows for the control of almost all devices (cameras, filter wheels, rotators, etc., including observatory domes) needed for local or remote astrophotography sessions.
The system also offers high flexibility for users who prefer to use traditional computer client applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools. This complete compatibility is ensured through the adoption of the Alpaca communication protocol, which allows for the use of traditional ASCOM platform drivers for native INDI devices.State-of-the-art mount construction
The BRESSER Nebula mounts are CNC-manufactured from stainless steel and aluminium. The sleek and functional design is courtesy of a renowned Italian mount manufacturer, who has licensed the design and now manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily portable mount, which despite its light weight of only 13 kg (incl. tripod), allows for a high load capacity of up to 20 kg.Visual Observation
For visual observation and direct use, control the mount with the hand control box included in the package. Alternatively, connect the Nebula 5 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be set via the web application. The user interface is deliberately simple and clear to ensure intuitive operation.Astrophotography
Here, the Nebula mount shows its full strength. Whether mobile or stationary, the capability for remote operation is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transmission) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed Kstars/EKOS software to control the mount and all external devices such as cameras, motor focus, filter wheel, etc. Alternatively, you can also directly control the unit with your own software. Applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools can be used without any issues.2-in-1 Mount with EQ and AZ Mode
If required, the Nebula can be switched from the equatorial mode to the azimuthal mode. This is particularly advantageous for observing nature or tracking satellites. Thus, the mount can be used for various applications and is not limited to astronomy.Attachment of up to two optics
Would you like to adapt multiple optics? No problem. Simply use the option to replace the counterweight bar with another telescope. Use the second optic as a counterweight to the main telescope. Set the Nebula 5 to azimuthal mode, remove the counterweight bar, and screw a suitable second telescope clamp directly onto the mount.
