Digital Setting Circles
Digital setting circles (DSC) consist of two rotary encoders on both axis of the telescope mount and a digital readout. They give a highly accurate readout of where the telescope is pointed and their lit display makes them easier to read in the dark. They have also been combined with microcomputers to give the observer a large database of celestial objects and even guide the observer in correctly pointing their telescope.
In contrast to a GOTO telescope mount, a mount equipped with DSC alone is sometimes called a "PUSH TO" mount.

Famous quotes containing the words setting and/or circles:
“Love is at the root of all healthy discipline. The desire to be loved is a powerful motivation for children to behave in ways that give their parents pleasure rather than displeasure. it may even be our own long-ago fear of losing our parents’ love that now sometimes makes us uneasy about setting and maintaining limits. We’re afraid we’ll lose the love of our children when we don’t let them have their way.”
—Fred Rogers (20th century)
“By the power elite, we refer to those political, economic, and military circles which as an intricate set of overlapping cliques share decisions having at least national consequences. In so far as national events are decided, the power elite are those who decide them.”
—C. Wright Mills (1916–1962)
