This refractor-based system starts off with a precision aligned ED doublet lens with a 100mm 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. - Inside this custom-made refractor, you'll find an internal etalon with tune adjustment which allows for a maximum of <0.75 Angstrom bandpass. You'll get a sharp, crisp ~7.3mm image through its a 34mm blocking filter, revealing excellent details on both the solar surface, limb edge, flares and prominences.
