During summer holidays I will not lay on beach but instead make myself familiar with the equipment we (TaUrsa) own. This setup consists of SXVR-H18 CCD-camera with external extra cooler, filter wheel with four 2" LRGB filters in place, sophisticated adaptive optics unit and Lodestar guide camera (OAG). Especially AO device is interesting and should be able to improve guiding accuracy and make imaging possible even in quite bad conditions. If I have installed all the pieces correctly together there are total of seven wires: 2 for power, 3 USB, guidecable and serial cable.
