A focal position corrector, extending the focal length of the system by a factor of 2x, with a filter thread, designed for astronomical binocular or binocular attachments. Moves the focus farther than the set Barlow 1.6x from the William Optics binoviewer kit (SKU: E-BINO-P). Thanks to this, it enables image sharpening in telescopes with a limited focusing range - for example for bright Newtons and photo-refractors.

Optically, it is a high-quality Barlow lens that can be screwed both into the nose of the binocular connector and into the filter threads of glasses with a 1.25 "frame.
