The POLARIE U is an ultra-compact automatic star tracking device that can be easily transported.In addition to the functions of conventional star trackers, which track a camera for a long exposures, accurately tracking the regular movement of celestial objects, the POLARIE U has a speed adjustment function, which allows it to be used as a panning mount too for time lapse photography.Using a smartphone, you can control the shutter release intervals of the images. Through the communication between the smartphone and the POLARIE U Star Tracker, you can control the exposures and take beautiful, sharp pictures of the stars and the Milky Way without getting any star trailing.The Star Tracker is very small and light weight, making it ideal for mobile use or air travel.The Vixen POLARIE U Star Tracker in detail:Star-scape photography (stars and landscape).A silhouetted landscape on earth is photographed together with the starry sky. The beauty of a landscape and the starry sky can be shown together on one photo. POLARIE U opens up a wonderful foreign world of star-scape photography and makes this possible for both beginners and advanced photographers.Conventional telescopic astrophotography photographs a relatively narrow area of the sky. Star-scape photography mainly uses a wide-angle lens and takes impressive photos in which stars, and other celestial targets such as the majestic Milky Way and landscapes are combined. The possibilities of the compositions are endless and a completely new kind of landscape photography opens up.Weight reduction of more than 20% and improved load capacity.The structure of the original POLARIE has been completely changed. The distance between the two bearings that support the rotating shaft is about four times the distance of the previous model. This leads to a higher load capacity despite the weight reduction of 20%. The maximum load capacity is 2.5 kg (approx. 2.5 kg at 10 cm from the centre of rotation) when used for wide-field astrophotography. The maximum load capacity is increased to 6.5 kg (approx. 6.5 kg at 10 cm from the centre of rotation) when a POLARIE Multi mounting block (optional) and a dovetail slide rail DD (optional) are combined. In addition, used in vertical configuration, the POLARIE U can reach a load capacity of 10 kg (approx. 10 kg 10 cm from the centre of rotation) for time-lapse photography and is therefore suitable for heavy camera equipment.Settings via SmartphoneCommunication between tracker and smartphone via the Vixen Polarie U App enables various settings via smartphones or tablet. For star/landscape photography, the speed is selected in user-defined mode, and for time-lapse photography, settings for interval time, exposure, and rotation speed can also be easily programmed.Five different speeds:Star-scape photography (half star speed). This setting is intended for displaying a landscape together with the starry sky. The stars are not tracked exactly, but slower in order not to blur the landscape in the foreground. This way you get beautiful images of the landscape and the starry sky.Wide Field Astrophotography (Star Speed)When this mode is selected, the POLARIE U follows the stars at the same speed as the daily movement of the stars. In this mode, widefield long time exposures of comets, nebulae, star clusters and the Milky Way are made and tracked precisely.Solar Tracking (solar speed)For recording solar eclipses over a long period of time.Moon Tracking (moon speed)For recording lunar eclipses over a long period of time.Custom ModeThis allows you to set the POLARIE U to the desired tracking speed. The initial setting is four times the star speed. If you want to change the setting for a different speed, a smartphone or other wifi device and application software are required.Shoot-Move-Shoot ModeIt is possible to stop the movement of the camera during the exposure and restart it after the end of the exposure. It is also equipped with a camera connector (shutter release) that controls the camera shutter during shooting with SMS or interval shooting. If the camera in use is connected with the cable release, the settings can be easily adjusted using a smartphone. A Wi-Fi connection is required when using this feature. An additional cable is required to connect the camera and POLARIE U together.Autoguider portCommercially available autoguiders can be used with the POLARIE U (Usable only in R.A.).  An important new feature over the original Polarie - attach a small Guidescope, or Off Axis Guider and autoguiding camera to your main camera and use the standard ST-4 protocol port to guide the Polarie U in Right Ascension, ensuring absolute accuracy of tracking (requires additional separate computer, or standalone guider). FEATURES    Speeds: Sidereal rate, 0.5X star speed, sun, moon.

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.
