Once again if you are one of the lucky few who have a Takahashi FC50mm apochromat, here is the chance to own the dedicated focal reducer F5.8. This long discontinued rare Takahashi accessory is in excellent condition with pristine optics. It can be used for both visual and photographic use and renders the most amazing pin point star images possible when coupled to an FC50/F8 fluorite refractor.
I am reluctanly lowering my price.
