Astro-Physics 16x70 Premium Binocular with Two Baader ASBF-70 Binocular Solar Filters

Binoculars are the perfect companion for the upcoming solar eclipse as well as your future nature studies and exploration of the night sky. We are pleased to offer our new 16x70 binocular to accompany you on your journeys or enjoy in your backyard. 

These 70mm binoculars will provide an outstanding and memorable view of the partial phases of the solar eclipse when coupled with appropriate solar filters on the front of the binocular. If you are lucky enough to be in the eclipse path, you will enjoy the full expanse of the corona in the wide field of view, solar prominences and pick up any stars and planets that appear in the darkened sky. Venus, Jupiter, Mars and Mercury will all be viewable during totality. Do NOT view the partial phases of the eclilpse without the proper solar filters or you will damage your eyes.
