Auriga presents the family of Premium Flat Field eyepieces with 60 ° apparent field (65 ° the PF15.5 model), 31.8mm barrel and FMC anti-reflection treatment. The Auriga PF series consists of three 5.5mm, 10.5mm and 15.5mm eyepieces respectively. The PF series eyepieces consist of 5 elements (6 for the PF5.5 model). The sophisticated optical scheme of which these eyepieces are composed guarantees an exceptional experience of use on any type of instrument. The planar apparent field of 60 ° represents the ideal compromise for those looking for eyepieces that are not excessively expensive in economic terms, but with outstanding performance and characteristics. The sharpness and contrast of these eyepieces will surprise even the most attentive and scrupulous observers. Incredible observations of the lunar, solar and even deep-sky objects await you. Observing the lunar craters through the PF Auriga eyepieces will be an unforgettable experience. The yield at the edges of the field is excellent and no spurious reflections or artifacts are observed. The FMC anti-reflective treatment guarantees very high levels of modulation in contrast with therefore sharp and bright images, well defined and without artifacts. The 31.8mm barrel is made of aluminum with CNC machines and is equipped with a comfortable rubber grip, for a firm and effective grip even when using gloves. Eye relief is 7mm for the 5.5mm model and 16mm for the 10.5 and 15.5 models.
