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.

The 360 IV Lens Heater is designed to prevent camera lenses and telescopes from fogging up due to dew. It is also well suited for eyepieces.The heating element is a carbon fiber heater with a high thermal efficiency. The textile heating element provides great flexibility compared to other heating materials. The power cord (USB cable) has a particularly high flexibility to be still elastic at low temperatures. A very flexible Velcro tape allows for quick and easy attachment to and removal from the lens. The tape can be easily removed from the lens without pulling tightly. The heating tape has a very low power consumption and can be operated with a 10,000 mA battery for up to 14 hours.The Vixen Lens Heater 360 IV in detailWhen moisture in the air comes into contact with an object whose temperature is lower than the ambient temperature, small drops of water form - so-called dew condensation. Astrophotography often suffers from such lens fogging and the photo turns milky. Because the temperature and humidity change during the night and the camera becomes cooler than the ambient temperature, it is important to warm the objective's or telescope's lens by using heaters to prevent it from fogging. We recommend using the Lens Heater 360 IV when you want to do astrophotography or night photography on the coast, in the mountains or in cold regions. The heating elements are made of carbon fibers with improved heating performance, introduced for the fourth generation Vixen Lens Heater 360 IV. They efficiently keep the lens warm and fog-free with minimal power consumption. The heater temperature reaches 10 degrees Celsius above the ambient temperature (at 20 °C outside temperature and no wind). However, it varies according to influences in the environment. For power supply the lens heater is equipped with a detachable coiled cable (USB Type-C), up to 50 cm long. The 360 IV lens heater consumes only 2.5 W of power (5 V - 0.5 A). With a portable USB battery of e.g. 10,000 mA, it can operate continuously for about 14 hours (at 20 °C outdoor temperature). However, the operating time varies greatly depending on the environment and temperature. The soft and non-slip surface of the heating tape allows for easy attachment to the objective, eyepiece or telescope. The heater consists of a 30 mm wide and 600 mm long heating tape and is suitable for diameters up to 100 mm.FEATURESHeating type: carbon fiber textile heatingTemperature: 10 degrees Celsius above ambient outdoor temperature (at 20° C, no wind)Power source, power consumption: USB, 5 V, 0.5 A, 2.5 WPower cable: USB A (male)Connector: USB type C connector detachable coiled cable 20 to 50 cmOperating time: approximately 14 hours with fully charged 10,000 mAh battery (at 20 °C outdoor temperature)Recommended for lenses with a width of 30 mm and an outer diameter of 45 to 100 mmDimensions: 30 x 600 mmTotal weight: 67 gSCOPE OF DELIVERYLens Heater 360 IVUSB spiral cable

High-performance flattener and reducer set connection rings for Vixen telescopes SD81S, SD103S and SD115S, as well as the ED predecessor series.
High-performance flattener and reducer set
The kit consists of a high-performance flattener, a reducer for reducing the focal length, and connection rings (distance ring SD81, EX Tube 66), which were developed for prime-focus astrophotography with the SD81S, SD103S and SD115S telescopes.
The flattener and the 0.79x reducer deliver a significant increase in telescope performance and image quality.
You obtain a flat and sharp image until the edges, including with a full-frame DSLR camera.
Ultra-sharp image over the entire field of view of the DSLR full-frame sensor
The SD flattener improves the image quality to the edge of the field of view without changing the original focal length of the telescope.
The field of view of the DSLR camera with a full-frame sensor is fully illuminated (44 mm), ensuring that stars appear sharp until the edges of the image.
When used in conjunction with the Reducer HD, the focal length is reduced by a factor of 0.79 (f/7.7→6.1) whilst maintaining the 44 mm illumination.
High-contrast AS coating
The anti-reflex AS coating, which is also used on our high-end VSD 100 f/3.8 astrograph, delivers a high light transmission of 99.9% per lens surface. Loss of light, ghosting and scattered light images are virtually eliminated thanks to the completely matte interior coating.
