Cercatore Skywatcher SW-7116 9x50 retroilluminato, immagine non invertita per telescopi

The Finder Scope Skywatcher SW-7116 9x50 is an optical accessory for telescopes that offers 9× magnification and a 50 mm objective lens. It provides a non-inverted image and features a backlit reticle to aid target acquisition in low-light conditions. Intended to speed up location and centering of celestial objects, this finder scope is compatible with a range of telescopes and is useful during visual observing sessions and alignment procedures for larger instruments.

Advantages

The 9× magnification gives a clear, wider-field view that helps locate stars, planets and deep-sky objects faster than a standard sighting tube. The 50 mm objective improves light gathering compared with smaller finders, enhancing visibility of faint field stars. The non-inverted image preserves upright orientation, simplifying manual pointing and visual reference with the naked-eye view. The backlit reticle allows precise centering in twilight or near-dark conditions, with adjustable illumination to suit different sky brightness levels.

Suitable for

• Locating and centering celestial targets before high-magnification observing
• Initial alignment of equatorial and alt-azimuth mounts
• Visual star-hopping and general observational sessions
• Use with refractors, reflectors and compound telescopes that accept 50 mm finder scopes

Key specifications

• Magnification: 9×
• Objective diameter: 50 mm
• Reticle: backlit for low-light use
• Image orientation: non-inverted (erect relative to naked-eye view)
• Optical purpose: wide-field target acquisition and centering

How to use

Mount the finder scope securely in the telescope’s finder shoe or bracket and tighten the adjustment screws. During daytime or with a distant terrestrial target, perform a coarse alignment by centering a distant object in both the main telescope and the finder. At night, perform fine alignment by centering a bright star or planet in the main telescope and adjusting the finder’s reticle until the same object is centered in the finder’s field. Use the reticle illumination control to set a comfortable brightness for your sky conditions.

Recommendations

For best results, complete an initial alignment each observing session and re-check alignment after significant temperature changes or transport. Use moderate reticle illumination to avoid glare and preserve dark-adapted vision; higher settings can be used for very faint stars or city-skies. Verify mechanical fit to your telescope’s finder mount before use and protect the objective lens with a cap when not in use.
