Sky-Watcher 6x30 straight illuminated finderscope
Product overview
The Sky-Watcher 6x30 straight finderscope with illuminated crosshairs is an essential accessory for astronomical telescopes. This high-quality finder features a 30mm achromatic doublet objective with anti-reflection coatings and a fixed eyepiece with illuminated crosshairs providing 6x magnification. The finderscope produces an inverted image both horizontally and vertically, which is standard for straight finders.

- Objective diameter: 30mm
- Achromatic doublet lens design
- Anti-reflection coatings for enhanced light transmission
- Illuminated crosshairs for precise targeting
- Straight-through design
- Focus adjustment via objective lens collar with locking ring
- Includes finder bracket with dovetail mounting
Technical advantages
Optical performance
The achromatic doublet objective effectively minimizes chromatic aberration, ensuring sharp and clear images across the field of view. The multi-layer anti-reflection coatings significantly reduce light loss and improve contrast, making faint objects easier to locate.
Illuminated crosshairs system
The built-in illumination system for the crosshairs allows comfortable use in various lighting conditions. The brightness can typically be adjusted to match ambient light levels, preventing the crosshairs from washing out in bright conditions or being too bright during dark sky observations.
Focusing mechanism
User focusing is achieved through the objective lens collar with a secure locking ring. This design provides precise focus adjustment while maintaining the finder's alignment once properly set.
Applications and compatibility
This finderscope is ideal for:
- Locating deep-sky objects
- Initial telescope alignment
- Navigation across star fields
- General astronomical observations
The included dovetail bracket ensures compatibility with most telescope tube rings and mounting systems. The 6x30 configuration provides an optimal balance between magnification and field of view, making it suitable for telescopes with focal lengths from 600mm to 2000mm.
Installation and setup
The finderscope mounts easily using the supplied bracket with dovetail attachment. Proper alignment with the main telescope is crucial for effective use. The finder should be aligned during daylight using a distant terrestrial object, then fine-tuned on a bright star during nighttime observations.
