Product information "Vixen SD Reducer HD Kit"
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.

Warning notes
- General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.

Vixen SG-L02 Headlamp red-light white-light
€69.00*
The perfect LED head torch for nighttime observations!
Adjusting your eyes to the dark surroundings is very important when making astronomical observations.
In dark areas, it is very difficult to use astronomical equipment without a suitable light.
With normal lights, however, the light intensity is more important than protecting your eyes against bright light.
Using these lights at night makes your pupils contract, which can make it difficult for your eyes to readjust to the darkness.
The SG-L01, our first astronomy LED lamp, featured a built-in red LED that provided a solution to this problem.
However, the red light did not offer optimal visibility. On our new astronomy LED light, the SG-L02, the LED lights produce warm light to improve visibility.
They also ensure that your eyes stay adapted to the dark.
The LEDs do not emit light in the sensitive range of 555 nm.
The brightness of the white light can be adjusted between 3 and 42 lumen, while the red light can be adjusted between 0.28 and 7.62 lumen.
FEATURES
Dimmable red light ensures that your eyes stay adapted to the dark
Built-in rechargeable battery, charges via USB
Waterproof design
LED colour can be switched from red to white
0.28 to 7.62 lumen for red light
