Imaging Session – 4th Nov 2021

Finally sorted out the focussing issue on the Esprit 120 setup – the cables were pulling on the Pegasus Powerbox Advanced causing the dew heater cables to keep shorting the power so the focuser kept disconnecting. 2 new cables installed and a re-calibration of the Sesto Senso Focuser and all back to normal.
