Orbinar – from astronomers for astronomers

Plossl eyepieces allow you to optimize the image quality of your telescope in a quick and easy way.

Our Plossl eyepieces stand out due to their reliable and proven quality; they thus provide a full chromatic correction and a better contrast.

This is possible thanks to their 4-elements coated lens system.

Of course, our Plossl eyepieces feature a screw thread that allows combining them with filters.

Delivery includes a protective receptacle for secure transportation and storage.

Magnification can be calculated by dividing the focal length of your telescope through the focal length of the used eyepiece.

What Magnification is this Eyepiece?
The magnification produced by an eyepiece depends on the optical system it is used in. In a standard astronomical telescope the magnification is found by dividing the focal length of the main tube by that of the eyepiece. For example, a 1000mm scope tube used with a 10mm eyepiece gives 1000/10 = 100x magnification. Used with a 5mm eyepiece gives 1000/5 = 200x.
