DobsonDream is a DSC controller (digital telescope guidance circles). It helps observers to

accurately and quickly find objects in the night sky. In this case, the telescope tube is pointed

to the object manually, until the crosshair in the planetarium program coincides with the

desired object. The controller receives data about the position of the telescope tube from

sensors (encoders) located on the telescope mount axes. As encoders, any quadrature

encoders with two TTL outputs and a power supply of 6 - 12V can be used. When

inexpensive low-resolution encoders are used, 200 to 2000 steps / pulses per revolution of

the encoder shaft, an additional gearbox is needed to increase the number of steps / pulses

per rotation of the telescope axis. In this case, the encoder will be installed radially to the

telescope mount axis, as in photo 1.

When using encoders with high resolution, 2000 - or more steps / pulses per one revolution

of the shaft, the encoder is mounted directly on the telescope mount axis, as in photo 2.
