Credible author

Hello. A credible authors' reference is being "overrided" by edit-warring. I recently tried to add to the telescope article but this  seems to think that his opinion overrides a VERY credible author in Mr. Richard Powers. I've been blocked before for edit-warring recently, so I don't want this to be another incident on my record. 

Anyway, the other editor seemed to have asked his friend-type editors to form a consensus, so I will do the same. The Islamic connection here is, Al-Haytham. He is FUNDAMENTAL to the telescope and the FATHER of optics. By definition, the summary can include him since the radio and electro-magnetic telescopes are derogatory to the average person looking at the article; I wanted to add it to the history section since it looked cleaner. Can you help your fellow InternetHero??
