This version of the focuser for Schmidt-Cassegrain telescopes is equipped with a Crayford system and accommodates both 50.8mm diameter eyepieces and 31.8mm eyepieces thanks to the Quick Lock adapter included with the focuser. The 50.8 / 31.8 adapter is locked thanks to the proven brass ring system, for maximum safety and reliability.

The Auriga image rectifier features a high quality Amici prism composed of BaK4 glass and with all surfaces treated with effective anti-reflective coatings, all to ensure maximum transmissibility and minimize the loss of brightness and contrast modulation.
