Featuring a fast f7.5 aperture ratio, the ED80Sf is ideal for both visual observers and astrophotographers. The optical system focuses the entire light spectrum onto one point, which reduces chromatic aberration to almost zero.
The colours are rendered neutrally with a high contrast.
The high contrast and excellent sharpness provide impressive images of the moon and planets.

- 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.
