TS Optics 25 mm Plössl Eyepiece with 1.25" barrel size and 50° apparent field of view

A good Plössl eyepiece outperforms a simple Kellner. We can offer this type of eyepiece at a price for which you would get only more simple eyepieces elsewhere. Nevertheless, the features are quite impressive.

The 25 mm Plössl is a very fine universal eyepiece for the overview. It satisfies with an excellent ease of view. For most binoviewers, a 25 mm Plössl is the optimal eyepiece, as the prisms do not illuminate more field as it is offered by this eyepiece. The entire field can be easily viewed with spectacles, no pressure necessary!

Areas of application of Plössl eyepieces

Through the four-element design, the Plössl is a true all-rounder. It does not introduce an additional chromatic aberration to the system, in opposite to more simple eyepieces with fewer elements. As a consequence, these eyepieces can be very well used for observing the moon and planets with higher magnifications.

At lower magnifications, Plössl eyepieces are well suited for observing nebulae, star clusters and galaxies, they convince with a field of view relatively free of distortion.

Astrophotographers can also work well with Plössl eyepieces, as they are well suited for eyepiece projection. The MgF2 coating prevents disturbing reflections and provide good contrast. However, many projection adapters are too narrow for the Plössl eyepieces with 32 or 40 mm focal length.
