... 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. ...

... We guess it's almost impossible to create the site nowadays where all space relative philatelic materials (postage stamps, stationary, postal marks etc.) would be registered and presented. ... We tried to make such a step in April 2005, placing at the site first images of postage stamps with portraits of astronauts (cosmonauts, spacionauts, taikonauts:). ... All illustrative material (or simply speaking, all scans of stamps) are grouped in four sections: Countries , Years , Astronauts and Flights . ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....
