... Большинству любителей недоступны крупные телескопы типа как Алькор и Мицар,и они останавливают свой выбор на таких недорогих компактных и моблильных инструметнах как зрительные трубы и монокуляры. Самые распространенные среди них - ЗРТ-457 и МП 20х60. За три года работы с этими инструментами я выявил не мало их скрытых достоинств, впрочем как и недостатков и хочу ниже в кратце рассказать о них. ... Поговорим об оптических достоинствах трубы. Они несколько хуже, чем у монокуляра. ...

Luckily, the poor weather stayed at bay and the DFM/JHU telescope was installed in the MT dome. ... A 136' crane arrived early in the morning and the telescope plate, fork, and mount were prepared to be lifted into the MT dome. The mounting plate and forks are lifted into the dome.

Next: Data reduction Up: Spectral observations and data Previous: Observations with the KPNO . Follow-up spectroscopy with this telescope was conducted as a back-up for a main program which needed photometric conditions. So, the observations presented here were obtained in non-photometric conditions and the absolute flux calibration of the data is unreliable. The Cassegrain focal reducer CAFOS of the 2.2m telescope was used with a long slit of 300 3 and a grism of 187 ? ...

In 1831, Giovanni Battista Amici , an optician from Modena, was invited by the Grand Duke Leopold II to preside as the Professor of Astronomy and to direct the "Specola", the observatory in Florence which was attached to the Royal Museum of Physics and Natural History. ... From that year, the telescope was used by Amici's young assistant, Giovan Battista Donati, mainly for observing comets and asteroids. ...
