The camera is equipped with a light-sensitive Charge Coupled Device (CCD), which allows to record two-dimensional images (called CCD frames). To achieve the highest possible precision of measuring the brightness of stars, the CCD is ​​cooled to -70°C. The cooling system is based on Peltier modules and an advanced control system. The camera resolution is 2048 x 2048 pixels. Each pixel has dimensions of 13.5 x 13.5 um.

The filter wheel is located in front of the CCD camera and allows to record images of stars in different color bands. Multi-color photometry is an important tool in observational astrophysics. Solaris telescopes are using Johnson U, B, V, R, I, and Sloan u’, g’, y’ and z’ filters. Filters have a diameter of 50 mm and are placed in a rotating wheel. A stepper motor positions the wheel so that the selected filter is located on the optical axis of the telescope.

The field rotator is located in front of the filter wheel and enables rotation of both – the camera and the filter wheel – around the optical axis of the telescope.

The telescope is mounted on a modified German equatorial mount equipped with two rotary axes driven by synchronous motors. High-resolution rotary encoders and an advanced control system allow to point the telescope at a given target on the sky. Stars and other objects (e.g. satellites, asteroids) can be tracked by the telescope with a speed corresponding to their apparent motion on the sky. The telescope is equipped with mirror covers protecting the main mirror when it is not observing and a focusing mechanism.

The flat field screen is used to calibrate the camera, shutter, and the optical system of the telescope. Evenly illuminated with controlled intensity, it allows to detect impurities and defects in the optics of the telescope, camera and filters, which then must be reduced in the data analysis process.

The weather station provides information about temperature, cloud base and precipitation. It is an essential element of the meteorological system ensuring the safety of the equipment during observations. The station is connected directly to the dome controller for high robustness.

The main weather station provides information about temperature, humidity, pressure, wind speed and direction and precipitation. Data from the weather station is processed by the control computer, which decides if the observations are possible or not.

The rack cabinet contains all the components necessary to operate the observatory: uninterruptible power supplies, manageable power distribution units, network infrastructure components, control computer and remote console.

The safety system oversees the operation of the observatory and controls ventilation and air conditioning systems. It also allows for an emergency shutdown of the observatory.

The manipulator is used to lift the calibration screen during the calibration process and to lower it after completing the procedure so that it does not interfere with the telescope’s field of view during regular observations.

Each dome is equipped with an air conditioner, which ensures that proper temperature and humidity are maintained in the dome and rack cabinet.

A monochrome IP-camera allows to view and record what is happening inside the dome from any location at any time.

The GPS antenna cooperates with the time card installed in a rack cabinet. It allows to record the time of opening and closing of the CCD camera’s shutter with microsecond precision.

The electric switchboard is fitted with circuit breakers and surge protectors.

The fisheye camera allows to record images of the entire sky. The 2PiSky system automatically analyzes the images. If clouds are detected, relevant information is sent to the control computer.
