Baader's new Super-wide 72 degrees 2" eyepieces feature Phantom-group multi-coating, internal baffling and aspheric elements for a remarkably high level of optical correction.

Light rays entering at the edges of conventional spherical lens elements converge at slightly different focal points to light rays entering from the centre. This is known as spherical aberration.  An aspheric lens has a non-spherical surface to converge central and peripheral light rays to a single focal point for uniform sharpness and clarity.

Both eyepieces offer a dual barrel configuration: The standard 2” barrel provides the full 72º field of view, and a special wide-field 1¼” barrel with a field stop of 1.265”(32mm) will extract the maximum field possible from 1.25” telescopes.

Baader have also been clever in that the 2" barrel is fitted via 24tpi SCT threads, which allows direct connection to the rear cell of popular SCT telescopes.
