TS Optics Ritchey-Chretien RC 304/2432 Pro Carbon OTA (56288)

This telescope is equipped with a carbon fibre tube, making it ideal for astrophotography while also being suitable for visual observation. The carbon fibre construction keeps the tube lightweight, which allows for use on smaller mounts. It provides excellent structural stability and minimal thermal expansion, ensuring the focus remains steady throughout the night—an essential feature for astrophotography. The dew shield is also made of carbon fibre and extends easily, while the interior of the tube is lined with black felt for optimal light absorption.
