... 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. ...
