... Формула, которая связывает эти физические явления и реальные кадры, которые мы отснимем на протяжении ночной фотосъемки такова: (1) Light = (Signal * Flat Signal) + Dark + Offset где Signal - это изображение целевого объекта, который мы хотим получить в идеальных условиях. ...

Однако, съемка Flat Dark-ов перед Flat Light-ами требует некоторых начальных знаний о том, какие ISO и Tv мы собираемся использовать для съемки Flat Light-ов. ...

... 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 . ...

... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...
