Introducing the Sharpstar Z4 100mm f/5.5 Telescope, a masterpiece in the world of astrophotography. Designed for both amateur and professional astronomers, this telescope stands out with its innovative sextuplet APO astrograph design, featuring a six-element, fully air-spaced lens system that includes two high-quality ED glasses. This sophisticated configuration ensures superior chromatic aberration correction, delivering crisp, clear, and true-colour images of celestial bodies.

The Sharpstar Z4 is not just about optical excellence; it also excels in user experience. It boasts a large 3.4-inch focuser, complemented by a 1:10 fine adjustment knob and a 360° rotator. This setup facilitates precise focusing and convenient angle adjustment, making it ideal for capturing stunning astro-images. Additionally, the telescope is equipped with versatile adapters, including M82, M68, M54, and M48 sizes, ensuring compatibility with a range of photographic accessories. The M48 adapter is specially designed with an internal thread to fit 2” filters, further enhancing its astrophotography capabilities.

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

With an aperture of 100mm and a focal ratio of f/5.5, the Sharpstar Z4 is capable of capturing wide-field images, making it perfect for deep-sky astrophotography. The telescope's 36mm image circle is optimally sized for modern astro-cameras, ensuring full-frame coverage without vignetting. The back focus of 55mm from the M48 thread is carefully calibrated for ease of use, eliminating the need for complicated back focus calculations. This feature, combined with the telescope's self-flattened optical system, means that users can focus on their target without worrying about image distortion.

Overall, the Sharpstar Z4 Telescope is a top-tier instrument for anyone passionate about astrophotography. Its combination of advanced optical technology, user-friendly features, and sleek design makes it a valuable asset for exploring and capturing the wonders of the night sky.
