I'm selling this Takahashi TOA-150 with a 67 Flattener and a Pentax 67 camera. The focuser is a Robofocus and I will include the control box and necessary cables. It has been used for some years before I acquired it and the coatings on the front element have some blemishes that should not affect optical quality but will bother you if you have OCD. Asking $17,500 or best offer.
