Schmidt–Cassegrain telescope
Hi, I reverted your edits at Schmidt–Cassegrain telescope because you are removing material attributed to reliable secondary sources and replacing it with material cited to primary sources (a patent). Please see WP:RS and WP:V on what type of citation Wikipedia accepts. I looked through the sources, and searched for more. Reliable sources say James Gilbert Baker first proposed a Schmidt–Cassegrain design in 1940. I see some reference to Roger Hayward building "a" Schmidt–Cassegrain at MWO, some atribute it to the whole optical shop, but no reliable source saying he was the first to invent it.
