  • The atmospheric dispersion corrector is born to increase the clarity of the planetary image by correcting the effects of dispersion of the earth’s atmosphere.
    The 2 high-quality 1/4λBK7 prisms with the fully-multi coated on each side act a pear performance in reducing the chromatic aberration. 
    The bubble level of the ADC is accurate to level the horizontal.
    A Barlow or planetary camera is permitted thanks to the 1.25” interface on two sides of the tube.
