Mira Skywatcher SW-7103 6x30 iluminada — visor ótico para telescópios

Finder Scope Skywatcher SW-7103 6x30 Illuminated is an optical sight designed to simplify locating and centering celestial objects on a telescope. It provides 6× magnification with a 30 mm objective lens and features an illuminated reticle for improved visibility in low-light conditions. The unit mounts to standard finder bases and is intended for visual observing, initial alignment and quick framing of targets before switching to the main instrument.

Advantages

The illuminated reticle offers adjustable brightness to match sky conditions and reduce eye strain during setup. A 6× magnification balances a wide field of view with enough detail to identify stars, planets and bright deep-sky objects. The 30 mm objective provides adequate light gathering for night use while keeping the finder compact and lightweight. Mechanical adjustments for windage and elevation allow precise centering and easy alignment with the telescope optical axis.

Suitable for

• Visual observers who need quick target acquisition before switching to higher-power eyepieces
• Amateur astronomers performing initial polar alignment or star alignment routines
• Users mounting accessories on standard finder shoe or bracket systems
• Observers working in low-light environments who require an illuminated aiming reticle

Key specifications

• Magnification: 6×
• Objective diameter: 30 mm
• Illuminated reticle with adjustable brightness
• Optical configuration: straight-through finder scope
• Manual windage and elevation adjustment controls
• Compact and lightweight housing suitable for most small to medium telescopes

How to use

Attach the finder to the telescope's finder shoe or bracket and secure it so the optical axis is stable. Switch on the illumination and set reticle brightness to a comfortable level for the ambient sky. During daytime or bright conditions, turn illumination off. Aim the telescope at a distant terrestrial object or a bright star and use the windage and elevation screws to center the object in the reticle. Once aligned, use the finder to place celestial targets in the field of view, then refine positioning with the telescope's main optics and eyepiece.

Recommendations

For reliable nighttime use, set reticle brightness low enough to preserve dark adaptation. Recheck alignment periodically, especially after transporting the telescope or changing mounts. Replace illumination batteries according to the manufacturer’s guidance and avoid exposing the finder optics to moisture; store in a dry, dust-free place when not in use.
