British observatory-planners are often faced with the long, narrow gardens of old terraced housing, in which a decent-sized observatory will often occupy the whole width of the land. To persuade other family members to accept that The Observatory Site percentage diminution of the available space may be difficult. However, the suggestions in the next section may help. Two common designs, to be described in Chapter 3, the run-off shed and the run-off roof observatory, effectively require twice as much space as the building itself, as the building, or its roof, move away from the telescope en bloc.
If using a desktop computer, there will need to be some means of taking the data away, probably to another computer indoors, for processing – in other words, either some kind of removable disk of sufficient capacity, or a wired or wireless local network. Few people will want to spend hours processing their observations in a cold observatory. The files generated by modern imaging methods are very large, often measured in gigabytes. A laptop gets around this, as it can just be taken inside with all the original data on its hard disk.
With stepper motors, the microprocessor board feeds pulses to the motor windings, which causes the speed to vary between rapid slewing from one part of the sky to another and precise tracking rate. Counting of the pulses sent allows the circuitry to predict how for the telescope has moved from an initial reference point, which allows it to keep track of position, and makes possible GOTO. There 21 22 Setting-up a Small Observatory need be no high voltage near the telescope, and the level of user-control is high, if all works correctly.
