The telescope tube made of carbon fiber reinforced polymer makes the telescope lighter and allows decreasing focal length dependency on temperature spans. Using carbon fiber reinforced polymer also makes for quick recovery of the thermodynamic equilibrium of the tube. As any other Ra telescope tube, the Ra R80 ED Doublet Carbon model provides high-quality clear views due to fully multi-coated optics. Moreover, this telescope has a dual-speed Crawford focuser that ensures high precision focusing with no backlash. With a sturdy aluminum case, this is a great addition that lets you store and transport your instrument with ease.
