Celestron Omni 4mm 1.25´´ eyepiece

These Plössl eyepieces from Celestron have all the necessary features for a good Plössl eyepiece. The eyepieces are the successors to the legendary Celestron NexStar Plössl.

Characteristics:

• Multiple bonusing of all lenses ensures good contrast and clear rendering
• Good optical quality for maximum possible sharpness across the entire field of view
• Black coated lens edges for more contrast of light objects
• Rubber blinders to suppress stray littoral light and to increase the comfort of personnel wearing glasses
• Pleasant interocular distance also with short focal lengths

Fields of application

Due to their design as a four-lens system, Plössl eyepieces no longer cause chromatic errors. Many simple telescopes are offered with three- or even two-lens eyepieces, which often cause chromatic errors and considerable contrast reductions. Plössl eyepieces can be used in a wide variety of ways, they are ideal for all types of astronomical and terrestrial observations.
