... Despite the use of counterweights, I have had ongoing problems with preventing unwanted motion in altitude, particularly during star parties when everyone seems to want to lean on the telescope while observing. ... After some difficulties at a windy star party a few years ago at the Boston Museum of Science, I designed a simple and very effective altitude brake and slow motion control which can be assembled very quickly and at minimal cost. ... The other end of the arm attaches to a turnbuckle*. ...

... 1) The MS lower envelopes for groups of stars with different metallicities turn out to be coincident. ... 4) The conformation of the kinematics of stars within narrow ranges ob b-y with the ages derived from isohrones reveals that, at Z < Z , the isohrone ages seem to be increasingly overestimated with growing b-y . ... At a given metallicity, they have a much narrower MS and the locus of their MS lower envelope seems to be brighter for the metal-rich group of stars. ...

... Дверь в Четвертое Измерение. ... Каких-либо мыслей по поднятому вопросу исследования и классификации Аномальных Зон (АЗ) у меня нет, а вот для приверженцев идеи, что АЗ - место перехода в другое пространство, измерение и т.п. хочу кое-какие логические простейшие соображения подкинуть (коль уж вопрос подняли). ... Выскажу такое логическое допущение, за которое вы меня не будете, я думаю, сильно бить: переход (возможно энергетически) выгодно производить в местах ПЕРЕСЕЧЕНИЯ пространств. ...
