The 25mm Kellner eyepiece delivers 30x magnification with a wide field of view—ideal for locating targets and observing extended objects like star clusters. The 10mm eyepiece increases magnification to 75x, revealing planetary details and tighter celestial structures. The theoretical maximum useful magnification reaches approximately 300x under ideal conditions.
Newtonian Advantages For Deep Space
The Newtonian reflector design offers significant advantages for deep-sky observation. Unlike refracting telescopes, reflectors avoid chromatic aberration (color fringing) regardless of target brightness. The unobstructed light path maximizes contrast when viewing faint galaxies and nebulae, while the relatively short tube enhances portability.
Performance Parameters And Limitations
Optimal viewing occurs between 30x and 200x magnification, depending on atmospheric conditions. The telescope performs effectively even in light-polluted suburban environments for lunar and planetary observation, though deep-sky objects benefit significantly from darker locations. The optical system resolves details as fine as 0.77 arc-seconds under ideal seeing conditions.
User-Friendly Design and Portability
The tabletop Dobsonian mount represents centuries of refinement in telescope design. The altazimuth configuration with Teflon bearings allows natural hand-guided movement without complicated controls. This tracking method follows how humans naturally point and observe, eliminating the learning curve associated with equatorial mounts.
Precision Targeting System
The integrated altitude tensioning system provides critical stability during observation. This feature allows users to adjust movement resistance based on the eyepiece weight, preventing the frustrating drift that plagues many portable telescopes. The result is steady viewing even at higher magnifications, where image stability becomes paramount.
Transportation Considerations
At 25 pounds (11.3 kg) total weight with dimensions of 19″ x 19″ x 18.5″ for the base, this telescope strikes a balance between aperture and mobility. The optical tube and base separate for transport, with no component exceeding 9 pounds.

The system requires no tools for assembly and functions without external power sources, making it ideal for impromptu stargazing sessions and remote locations.
Durability Factors
The solid-state design with minimal moving parts enhances long-term reliability. The primary mirror features an aluminum coating with a protective SiO2 overcoating for extended reflectivity. The tabletop base uses high-density fiberboard resistant to moisture and temperature variations, while metal components receive corrosion-resistant treatments for extended outdoor use.
What You Can See: Real-World Observation Capabilities
The Moon transforms into a dramatic landscape of craters, mountain ranges, and valleys. At 75x magnification, features as small as 3-4 miles across become visible. Observers can clearly distinguish the Apennine Mountains, the ray system of Tycho Crater, and the terraced walls of Copernicus. The terminator line—where sunlight meets lunar night—reveals dramatic shadows highlighting topographical features.
Solar System Discoveries
Jupiter displays its atmospheric bands and Great Red Spot under good seeing conditions, along with the dance of its four Galilean moons. Saturn’s rings appear distinctly separated from the planet, with the Cassini Division visible during steady atmospheric moments. Mars reveals polar ice caps and major surface features during opposition, while Venus clearly shows its crescent phases.
Beyond Our Solar System
The telescope excels at revealing deep-sky wonders. The Andromeda Galaxy (M31) appears as an elongated fuzzy patch with a brighter central core. The Orion Nebula (M42) displays wispy cloud structures surrounding the trapezium star cluster at its heart. The Pleiades cluster (M45) transforms from seven visible stars to dozens of sparkling points against a dark background.
Urban vs. Dark Sky Performance
From suburban environments, the telescope effectively reveals lunar details, planets, bright star clusters, and about 25-30 prominent deep-sky objects. When transported to dark sky locations, the observation potential expands dramatically to hundreds of galaxies, nebulae, and clusters, with significantly enhanced contrast and detail.
Seasonal Viewing Strategy
Winter skies offer exceptional views of the Orion Nebula, Pleiades, and multiple star clusters. Spring brings the galaxy fields of Virgo and Leo into optimal position. Summer highlights include the Milky Way core with numerous globular clusters and nebulae. Fall presents the Andromeda Galaxy and the Perseus Double Cluster at their best. Planning observations around these seasonal targets maximizes the telescope’s capabilities.
