The SkyLine Deluxe’s far-reaching beam is visible not only by the person holding the pointer, but also by others standing several feet to the side. It works even in light-polluted or moonlit skies, though dark skies a

Shortens the focal length from 900mm to 765mm (f/9.0 to f/7.65). installing the reducer-corrector 1. Extend the focuser drawtube out, as shown in Fig. 1. 2. Rotate the lock ring inward on the focuser drawtube until it stops (Fig. 2). Do not tighten. 3. Screw the Reducer-Corrector onto the drawtube until it stops, and tighten it slightly.
