The APM Ultra Flat Field eyepiece series is a further development in the field of field correction and viewing comfort. The performance of the newly calculated optics is compared in view of the great price. In particular, the details of the optics, such as high-quality FMC multi-coating and effective internal blackening of the optical and housing components, produce a high-contrast, pure-color and sharp image. Our UFL can rightly be called "little stars".
Our model UFL 30mm 2" delivers a medium field of view. A very good compromise between field of view and correction capability. So, it is a very good all-in-one eyepiece of 2" barrel size. The AP is 22mm and is universal. The optical construction consists of 9 lenses in 5 groups.
