High-end Zeiss microscope binoviewer modified for use with telescope. Comes with 2X lens (removable), 1-1/4" and 2" adapters, and 2 matched sets of high quality EP's for a total
of 4 power settings equivalent to 8, 16, 25 & 50mm focal lenths. Compact size straight-thru binoviewer is constructed from high quality components including, focusing diopters (both barrels) and gaged spacing (ref photo). I used this viewer with an unforgiving .21A HA filter and views were still sharp. FOV is only 15% less than new Baader Mk5, but selling at a fraction of the cost. This is an excellent value at $200 firm. Many thanks for consideration!
