Can Einstein-Chwolson rings be observed from a telescope on Earth?

[QUOTE="KurtLudwig, post: 6447076, member: 639757"] Thanks for the link. I have read the article of the above link, and the observation of doctoral researcher Margharita Bettinelli. Are radio telescopes more sensitive than optical telescopes since microwaves are less absorbed by clouds and water vapor in the air? It must take a very high-powered reflective telescope to to see a source galaxy 8.5 billion light years from Earth. And it must be located on a mountain top in Chile where there is very little light pollution and water vapor in the atmosphere. [/QUOTE]
