Key specifications Focus ratio: F12 Maximum magnification: 300 times Optical system: combined refractive and reflective Caliber: 127 mm Why this telescope matters Larger aperture for brighter, clearer views: The 127 mm caliber gathers significant light, improving contrast and detail compared to smaller instruments. This supports clearer observations of the Moon, planets, and brighter deep sky objects. Long focal ratio for contrast, magnification viewing: The F12 focal ratio produces a longer focal length and helps minimize optical aberrations, making it well suited for detailed lunar and planetary observation at higher magnifications. Versatile optical design: The combined refractive and reflective system leverages the strengths of both lens and mirror elements to deliver a balance of image sharpness and practical length, helping reduce chromatic and spherical aberrations. Performance highlights Reach magnifications: Capable of up to 300 times magnification for detailed views of planetary features and lunar surface structure. Actual usable magnification depends on atmospheric seeing and the eyepiece or camera used. Stable, contrast images: The F12 configuration and the optical combination support crisp, contrast images useful for closeup observation and imaging of small targets. Solid light gathering: The 127 mm aperture improves resolution and brightness, aiding the identification of planetary bands, lunar craters, and close double stars. Function and compatibility Designed for serious visual observation and planetary imaging when paired with suitable eyepieces or imaging equipment. Compatible with standard astronomical accessories and mounts that support a 127 mm class optical tube. Verify accessory interfaces before for camera adapters or specialized eyepieces. Practical for both backyard observers and users who want to step up from entrylevel telescopes without moving to larger, heavier systems. Use scenarios Lunar and planetary observing: Use higher magnifications to inspect crater detail, planetary bands, and polar regions on planets when atmospheric conditions permit. Double star and small deepsky detail work: The combination of aperture and focal ratio helps resolve close double stars and improve the visibility of compact nebulae and star clusters. magnification terrestrial observation and imaging: With the right eyepiece and mount, the optical system can be used for distant terrestrial viewing or for targeted astrophotography of planets and the Moon. What to expect in real use Performance scales with observing conditions and accessories. Good results are achieved when the telescope is mounted on a stable tracking or equatorial mount and paired with appropriate eyepieces or imaging equipment. The long focal ratio favors higherpower views and detailed targets rather than widefield deepsky imaging. This telescope provides a combination of a 127 mm aperture, F12 focal ratio, a refractive and reflective optical design, and up to 300 times magnification, making it a practical choice for users focused on detailed lunar and planetary observing and targeted imaging.
