An eyepiece is part of the optical system in astronomical telescopes. The eyepiece is attached to the telescope and enables the view. It enlarges the image produced by the telescope, similar to a magnifying glass.
FOCAL LENGTH AND MAGNIFICATION
The focal length of the eyepiece used, along with the focal length of the telescope, determines the magnification. This can be calculated easily with the following formula:
Magnification = Focal Length Telescope : Focal Length Eyepiece
Example: Telescope 1000mm : Eyepiece 6.3mm = 159x Magnification
In general: the shorter the focal length of the eyepiece, the higher the magnification. Furthermore, the longer the focal length of the telescope, the higher the magnification. Eyepieces with longer focal lengths provide a better overview of the night sky.
PLÖSSL CONSTRUCTION
The construction of the eyepiece is decisive for the optical quality of the eyepiece. The Plössl construction delivers very good optical results. It is a four-lens construction. Colour aberrations are drastically reduced. Plössl eyepieces provide very good image sharpness and high contrast for great viewing pleasure.
FULLY COATED
The full coating (FC) of the lenses enables improved light transmission for the brightest possible image. The coating also reduces reflections.
1.25" CONNECTION
All DÖRR eyepieces feature a standardized 1.25" diameter. That corresponds to 31.7mm. The rear side is fitted with a thread to attach a moon filter (optional accessory).
