A zoom eyepiece is an eyepiece for telescopes or binoculars where the focal length can be adjusted continuously. This allows you to adapt the magnification to the observation object without changing the eyepiece.
The eyepiece fits all common telescopes and spotting scopes with a 1.25-inch eyepiece holder. Binoculars with interchangeable eyepiece systems (e.g., Dörr Danubia spotting scopes) are also compatible.
The focal length can be adjusted continuously from 7 mm to 21 mm. The shorter the focal length, the stronger the magnification.
The package contains the Dörr Danubia zoom eyepiece only. A storage box or lens cap are not included in the standard delivery – please check the product description from the retailer.
Store the eyepiece dust-free. Clean the lens surfaces if necessary with a soft brush or microfiber cloth. Avoid aggressive cleaning agents.
