Дополнительная информация из книги: R.N. Wilson "Reflecting Telescope Optics I" Second Edition. Springer. 2007. На странице 440 в последнем абзаце есть следующий текст:
"Although of smaller size, two telescopes by Carl Zeiss Jena were noteworthy, a 1 m, f/3.0 telescope for Bergedorf in 1911, and a 1.22 m with Newton f/6.9 and Cassegrain f/19.7 in 1915. The latter (subsequently moved to the Crimea) was the largest telescope in Europe for 30 years, but, in contrast to the very short telescope for Bergedorf, was an
outdated optical concept (too long) compared with Ritcheys telescopes."
