The FPL53 glass reproduces an extremely clear and sharp image by eliminating residual chromatic aberration.
Another advantage of these SD refractors is their short length and lightweight design.
The SD glass is designed to focus all beams of violet, red, blue, yellow and green light exactly onto the same level.
The special lens material reduces chromatic aberration across all colours.
Together with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors provide illumination with a 44 mm image circle for full-frame SLR cameras.

- 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.
