DSCs, or digital setting circles, are electronic gadgets. Two rotary encoders are present on every telescope axis. A digital readout provides precise data. Reading in the dark is made simple by the illuminated display. DSCs are an advanced solution for traditional setup circles. These circles have graduated scales and are mechanical devices. They were employed to adjust the position of the telescope manually.

Digital setting circles are makings on a telescope’s mount that help you point the telescope towards a particular object. Many telescope-setting circles need to be bigger or better marked to be helpful. The digital setting circle aids in pointing the telescope by utilizing rotary encoders attached to the telescope’s axes. A computer monitors this movement and continuously reports the telescope’s direction to the user.

Applications of Digital Setting Circles:

Digital setting circles enhance the efficiency, accuracy and convenience of amateur astronomy and making celestial observation to a broader range of enthusiasts.

Research Telescope:

Historically setting circles have rivaled the telescope as far as difficulty in construction. It has a large diameter and when combined with a vernier scale could point a telescope to nearly an arc minute of accuracy. In the 20th century setting circles were placed with electronic encoders on most research telescopes.

Object location:

The digital setting circles is to assist users in locating celestial objects in the night sky such as, star, planet or deep sky object.

Time saving:

Digital setting circles reduce the time it takes for astronomers to locate celestial objects and user can move from one target to another without the need for manual adjustment.

Improved Accuracy:

DSC systems provide accurate position information, reduce the likelihood of human error when manually setting telescope coordinates.

Educational Tool:

DSC systems can serve as educational tools for amateur astronomers and help them to learn about celestial coordinates, stars and the mechanics of telescope movement.


This integration allows for a more automated stargazing experience, where the telescope can be automatically aligned with specific celestial objects based on the input from the digital setting circles.

Remote Observing:

Digital setting circle system can be connected to computers or mobile devices, enabling remote control of the telescope.

Custom Catalogs:

Many DSC systems allow users to create custom object catalogs, adding specific celestial objects or targets of interest. This flexibility is valuable for astronomers who want to explore specific regions of the sky or focus on particular types of objects

Astronomical Research:

Digital setting circle is design for the amateur astronomers, and it can also useful for more serious astronomical research.

How digital setting circles work?

Position Sensors:

Digital setting circles include sensors, such as encoders or sensor based on the other technologies and measure the telescope’s position in both axes.


The position data from the sensor is sent to a computer interface and microcontroller.

Database of celestial Objects:

The digital setting circle device is preloaded with a data base of celestial objects, such as stars, planets and other deep-sky objects.

User Input:

The celestial object using a keypad and some form of user interface and it can control by a connected computer or smartphones.


This device calculating the current position of the telescope and the target object’s coordinates.

Guidance system:

The digital setting circle system then guides the user by providing the instructions on how to move the telescope in both axes.

Digital Setting Circles are useful for:

  • To find faint objects.
  • To find objects in light polluted sky.
  • Identify objects
  • Preserve an astronomer’s patience.


Digital setting circles (DSC) are essential instruments in modern professional astronomy. They improve convenience, accuracy, and efficiency. They provide celestial observing to a broader audience of people.
