Introducing the Sharpstar Z4 100mm f/5.5 Telescope, a remarkable instrument designed for astrophotography enthusiasts of all levels. This telescope stands out with its innovative sextuplet APO astrograph design, featuring a six-element, fully air-spaced lens system that incorporates two high-quality ED glasses. This advanced optical configuration ensures exceptional chromatic aberration correction, providing clear, crisp, and true-color images of celestial bodies.

This telescope is crafted not only for optical excellence but also for an enhanced user experience. It includes a large 3.4-inch focuser, complemented by a 1:10 fine adjustment knob and a 360° rotator. This setup allows for precise focusing and convenient angle adjustments, making it ideal for capturing stunning astrophotographs. The telescope also comes equipped with versatile adapters, including M82, M68, M54, and M48 sizes, ensuring compatibility with a range of photographic accessories. The M48 adapter, in particular, features an internal thread to accommodate 2” filters, further enhancing its astrophotography capabilities.

Weighing only 4.3kg, the Sharpstar Z4 is surprisingly lightweight for its class, making it easy to handle and transport. The sleek design is accentuated by a matte grey coating, providing a modern and professional look. The light grey lens tube, paired with the dark grey focuser and tube ring, adds to its aesthetic appeal. The tube ring includes a convenient handle, simplifying assembly and transportation, and features a Vixen-style finder slot for additional accessory mounting.

With an aperture of 100mm and a focal ratio of f/5.5, this telescope excels at capturing wide-field images, making it perfect for deep-sky astrophotography. The telescope's 36mm image circle is ideally sized for modern astro-cameras, ensuring full-frame coverage without vignetting.
