The brand new Spectrum 60 Upgrade for your PST! Increases objective aperture by 50% for substantial gains in resolution. Up-sizes your blocking filter by 100% from 5mm to 10mm for a brighter, wider field to accommodate the larger and more detailed image created by the new 60mm F/10 S-60 objective lens! It really works!!
