Q: 3. Any hands-on reviews of 15x70 ED vs. 20x80 ED, and pros & cons of each? Which is better for astro’ viewing?
A: The Celestron 20x80 SkyMaster Pro ED Binoculars are brighter and have more magnification than the Celestron 15x70 SkyMaster Pro ED Binoculars, and are better for "Astro Viewing"; users will agree.
