The new Aero eyepieces from Skywatcher
These 2" Aero SWA eyepieces are designed with six lens elements in four groups. The employment of exotic ED glass significantly reduces chromatic aberration. The eyepieces deliver virtually distortion-free images over their entire impressive 68° field of view. All air-glass surfaces are multi-coated to improve light transmittance and contrast. All models feature blackened lens edges and are parfocal. The eyepiece barrels include a thread for accepting 2" standard filters. They have twist-up rubber eyecups and provide generous eye relief for spectacle wearers. The lens body is designed in attractive anodized aluminium with a knurled rubber grip.
