Editing Altazimuth mount (section)

====Research telescopes====
In the [[list of largest optical reflecting telescopes|largest telescopes]], the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts.<ref>{{cite book |url=https://books.google.com/books?id=wXCMYy0yF5cC&q=altazimuth+mounts+have+been&pg=PA147 |first1=Pierre |last1=Léna |first2=François |last2=Lebrun |first3=François |last3=Mignard |title=Observational astrophysics |page=147 |isbn=9783540634829 |date=1998-01-01}}</ref> The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms.<ref>{{cite journal |last1=Dawe |first1=J.
