Baader M84/M68 Adapter for Pentax Refractors
The Pentax Adapter (BA-PXM84M68) converts the Pentax 100, 105, and 125 down from the large 84mm thread to a 68mm thread, and then the Baader 4-in-1 Adapter
(sold separately) will reduce the opening from 68mm down to 2" .
These two pieces offer a system that is significantly shorter in profile than the standard Pentax 2" Adapter, providing more focus range for visual, photographic, and CCD needs.
