Product description

The compact yet powerful 71 mm Gran Turismo refractor with the FPL53 triplet lens stands for best chromatic correction. Due to high-quality mechanics the refractor can be used in many ways.The Gran Turismo is ideally suited for mobile use. With a weight of only 2.2 kg, the refractor can be mounted on portable mounts such as the Skywatcher Star Adventurer or the iOptron Skyguider. Even good photo tripods are suitable for landscape observation. 

  • The carrying handle is a real multi-functional part. It facilitates the mounting of the apo on the tripod. At the same time, the handle also offers connection possibilities for mini guide scopes or finder scopes.
  • Visual observation: The refractor allows magnifications of up to about 200x with color-clear images. You can use 2" and 1.25" diagonals and thus have a magnification range from 20x to 200x available. Everything is possible from large field observation to the observation of details in the moon craters.
  • For astrophotography and landscape photography the 0.8x Reducer and Corrector P-Flat6AIII is an optimal additional part. The corrector improves the focal ratio to f/4.72 and offers a very good correction right into the corners, even with full frame format. The working distance from the M48 thread is 55 mm. A specially calculated Bahtinov mask for precise focusing is included.
