William Optics Apochromatic Refractor AP 61/360 ZenithStar ZS61 II OTA

Z 61: Small can be this beautiful

The new ZenithStar 61 and William Optics’ most versatile and lightest weight apochromats.

Its clear optics allow high magnifications and sharp imaging during astrophotography and nature photography using any SLR camera. Thanks to its large visual field, the entire Moon or (with a filter) the Sun can be viewed at once. A special flattener for photography is available in the accessories section.

The FPL-53 glass, which is built into the ZenithStar 61’s lens, has considerably better dispersion properties than the previously used FPL-51 (ED). FPL-53 is very close to fluoride glass in terms of quality but is considerably cheaper. Therefore, FPL-53 is sometimes also referred to as synthetic fluoride.
