This beautiful 86 mm f/6.5 ED APO Triplet Refractor by Founder Optics includes not one but two ED APO lenses for amazingly sharp and clear images!  One of the lenses is made with FPL53 glass and the other is designed with FPL51 glass.  The lenses are widely spaced and fully multi coated for protection and to further enhance the views to a very low distortion level of just -0.016%.  Founder Optics was not messing around!  

The FOT86 has a focal length of 560 mm.  Included in the custom foam-lined aluminum case is the scope itself with tube ring and easy-grip crank handle, a shoe ready to accept a finderscope, a Field Flattener with an M42 thread, M48 adapter, and dovetail.  

The optical tube is made of aluminum and the patented hybrid-style dual speed 2" rack and pinion focuser can carry a load of up to 8kg.
