Preparation


In this section you can find information about preparing to observation. And something about problems, which met us. At first we needed telescope. In this instant our school helped us. They bought telescope, which is 80 cm long and diameter of mirror is 20 cm. That was satisfactored for our purposes. We didn't interested in magnification, because we selected way of projection and it was best method for us. And we had first problem with screen where we would see Sun and Venus. Fortunately in our school are pupils, who are able to make it without problems. While our friend is making the screen we met several times and we were thinking about observation and area, where we will observe from. Then we hit upon the question "How long will be the observation?" Our professor told us, that it will take nearly 5 hours and it will start at 5o'clock(Am). But he forgot on heterochorism. Then we tried to solve problem with turning the telescope, because before now we turned it by hand. Fortunately Mr. Žíla managed it and we could start constructing telescope, but anybody didn't know which part belong to. We didn't have any manual, so it was hard work. It looked like prepared, but as always -it wasn't. We still didn't have a place, from we'll observe. At last we chose the area of school. It was good we had all necessary things near us. When we last met with professor it was one day before observation. At 8o'clock we started to prepare telescope and we had to wait to time, when sky became dark. We waited for Polestar, because it is necessary to detected north and put telescope to right position. We did it and because we couldn't leave telescope outside from school, we had to indicate points, where the tripod stood. But it wasn't particular, because the next day the picture on the screen bowled along, so we must tune it by hand. And that's all about preparing.
