This is an update on Dr. Don Bruns’s attempt to measure star-position deflection with our Tele Vue-NP101is telescope during this past August’s solar eclipse. His goal was not just to duplicate the famous 1919 experiment (by Sir Arthur Eddington that proved Dr. Einstein’s General Theory of Relativity), but to demonstrate that portable, readily available amateur equipment can produce results that rival that of professional hardware from past decades. His experiment was to “determine Einstein’s deflection to an accuracy of 1%, the best optical measurement of the deflection ever demonstrated.” He points out that a professional attempt at the 1973 eclipse achieved an error of 11%. See our blog post “Tele Vue NP101is to Test Einstein’s General Relativity” for more background.
We’d like to share with you this nice letter Al received from Roger Harvey recently.
This is the counterpoint to our Tele Vue is for the Birds blog post this past spring. Yes, you’ll find that the TV-60 is a great grab’n go astro scope too!
Our award winning, high performance, super-compact Tele Vue-60 is worth considering for those looking for a super-portable APO refractor. It fills many niches including travel, super-finder, day/night scope, and is a great telephoto.
It accomplishes all this APO-goodness in a very small 60mm, f/6 form-factor: just 10″ long without diagonal!
