The Focal 20-20-601 refractor telescope is an excellent choice for those seeking a versatile and powerful instrument for astronomical observation. This telescope boasts a 60mm achromatic coated lens, which provides a generous 30mm objective aperture and allows for an impressive 15x magnification.
The achromatic coating on the lens ensures that the telescope delivers sharp, clear, and color-corrected images, making it an ideal tool for observing a wide range of celestial objects. The lens also features a multi-coated anti-reflection coating that minimizes light loss and enhances the overall brightness and contrast of the images.
With a focal length of 20 inches (508mm), this refractor telescope offers a relatively long focal length, making it a great choice for those interested in lunar and planetary observation. The long focal length also results in a narrow field of view, which can be beneficial for focusing on specific targets and reducing the amount of unwanted background light.
The telescope comes with a 1.25" Crayford-style focuser, which provides smooth and precise focusing adjustments. The focuser features a 1.25" eyepiece holder that can accommodate various eyepiece types and magnifications, allowing users to customize their observing experience.
Additionally, the Focal 20-20-601 refractor telescope comes with a sturdy and lightweight aluminum tube construction, which ensures stability and durability. The telescope also includes a finderscope, a collimation tool, and a carrying case, making it a complete observing system that is easy to transport and set up.
Overall, the Focal 20-20-601 refractor telescope is an excellent value for those seeking a powerful and versatile telescope for astronomy observation. Its achromatic coated lens, long focal length, and precise focusing capabilities make it a great choice for lunar and planetary observation, while its durable construction and included accessories make it a practical and convenient option for both beginners and experienced astronomers.
