During totality of the 2017 total solar eclipse, he have a lifetime! imaged stars near the Sun, attempting to make the most accurate optical measurement to date of Einstein's prediction that starlight will deflect by 1.75 arcseconds divided by its distance from the sun as measured in solar radii. "My results were looking so good I needed to calculate the theoretical value to a few more decimal places: 1.7512 arcseconds to be exact. After careful analysis of my eclipse images, my final deflection constant measured exactly 1.7512 arcseconds. A perfect conclusion to a perfect eclipse!" From creating scientific history to family memories, Tele Vue's line of APO refractors are proven performers. Let us build an heirloom-quality instrument for you.
