The automation of your dome travel is explained below. Spherical panoramic visuals of The within with the observatory see here

As a way to acquire empirical facts for that exceptional adjustment of our dome air-con, you can find now many measurement sensor for detection of temperature and humidity. The temperature of the big Main mirror is measured immediately to the mirror and will normally be in contrast Along with the indoor and outside temperature. The goal is to minimize the commonly needed cooling of the telescope by using the dome air-con. By detecting the dampness in the mirror mobile and the dome inside, it is achievable to avoid dew during the dehumidification manner. Other sensors are a similar for cooling while in the icebox in the "massive air dryer" and The brand new twenty liter cold water tank close to the immersion evaporator of your air conditioning.
