The Apertura 75Q no-fuss telescope features apochromatic lenses for sharp, color-corrected images across a full-frame sensor. The quintuplet design ensures a flat field without the need for backspacing calculations or collimation, making it a plug-and-play option for stunning astrophotography.

The Apertura 75Q Refractor Telescope, powered by SharpStar, is tailor-made for astrophotography enthusiasts, whether novices or experts. This quintuplet refractor features fully corrected optics that provide near-perfect color correction and are optimized for full-frame sensors without the need for additional flatteners. Crafted using premium HOYA FCD-100 Glass, known for its low-light dispersion and excellent color correction, the 75Q offers sharper and higher-contrast images. With a focal ratio of f/5.4 and 405 mm focal length, it makes capturing your celestial targets straightforward and pairs seamlessly with both APS-C and full-frame cameras.

Key features of the SharpStar Apertura 75Q:

  • Integrated Petzval Design: Simplifies the imaging setup by reducing the need for precise back focus spacing, allowing for optimal performance as long as the camera reaches focus.
  • Built-in 2" Filter Cell: Enhances convenience by integrating a filter directly into the telescope’s optical train, eliminating the need for external accessories and making filter changes quick and easy.
  • Adaptability for Automation: Ready for use with electronic autofocusing systems like ASIAIR, facilitating hands-free and precise focusing during imaging sessions.


The Apertura 75Q also comes with robust support and warranty options. The Apertura Absolute Warranty covers any product defects for two years and includes a Three-Year Accident Replacement Program post-warranty. Additionally, the warranty is transferable, which is beneficial for maintaining value and assurance in the product’s performance over time. This comprehensive support, coupled with advanced optical capabilities, makes the Apertura 75Q an excellent investment for dedicated astrophotographers.
