Top finder scope with upright field, illumination, 90° viewing angle, and polar finder engraving. The image sharpness and viewing behavior elevate this finder significantly above the level of typical 8x50 finder scopes. The upright image field facilitates orientation. Multi-coating on all surfaces. This polar finder is primarily designed for users with portable telescopes. The 90° viewing angle makes operation easier, and with the help of the polar scale and illumination, a telescope can be quickly and accurately aligned to the celestial pole. The upright image field, combined with high image sharpness, makes handling a pleasant experience. The illumination is powered by two LR41 button cells.
