This product is in excellent condition. The glass is spotless, and the focus knobs are very smooth. The only wear on the telescope is some cosmetic blemishes on the paint.
Product Overview:
- Aperture: 120mm (4.7 inches)
- Optical Design: Neo-Achromat refractor, a variant of achromatic refractors with better color correction.
- Focal Length: Typically around 800mm (depending on the exact model).
- Focal Ratio: f/6.7, making it a relatively fast telescope, which is great for wide-field observations and astrophotography.
- Lens Configuration: Doublet or triplet lenses, designed to reduce chromatic aberration more than standard achromats.
Performance:
- Optical Coatings: Multi-coated lenses improve light transmission and reduce reflections, leading to bright and clear images.
- High Contrast: The design emphasizes delivering sharp, high-contrast views of celestial objects like the Moon, planets, and star clusters.
- Wide Field of View: Ideal for observing large areas of the sky, such as the Milky Way or open star clusters.
Physical Features:
- Construction: Made with high-quality materials, ensuring durability and ease of use. It typically features a lightweight aluminum tube.
- Weight: Generally in the range of 10-15 pounds, making it portable and easy to mount on a variety of mounts, including equatorial and alt-azimuth.
- Mount Compatibility: The tube often comes with a dovetail mounting plate compatible with Vixen-style mounts.
- Dew Shield: Usually includes an integrated dew shield to prevent moisture from affecting the optics during long observation sessions.
Use Case:
- Visual Observation: Provides excellent views of the Moon, planets (such as Jupiter and Saturn), and deep-sky objects like nebulae and galaxies, thanks to its wide aperture and superior color correction.
- Astrophotography: Its relatively fast focal ratio makes it well-suited for astrophotography, especially wide-field imaging of star fields, nebulae, and galaxies.
