This refractor-based system has a precision-aligned singlet chromatical lens with a 60mm aperture. The front singlet lens reduces half of the stray light of an achromat and it fully eliminates the possibility of an on axis coma, astigmatism, de-centering aberrations. It provides with the matched collimation lens set a full spherical corrected flat-field. The focal length is 500mm providing a ~4.5mm image through a 6mm blocking filter. Course focus adjustment via a slide tube. Fine adjustment is achieved with a Crayford-style focuser with 10:1 reduction standard.
