Supernova SN2014L in Messier 99 (Virgo)

SN2014L is a supernova in the galaxy M99
During the image acquisition, the CCD camera was working at -42,3°C. That means amazing 45°C under the ambient temperature, a value which far exceeds the specification of this camera. The dark noise of the QHY8L was almost not noticable at this temperature. Hence, I did not use any dark frames to calibrate the sub-exposures.
