Ngc 5247

Hello, this is four hours and 15minutes of 300sec (five minute) subs with darks and bias frames. Canon 5d mark II and RC 10 with it's original focuser.
I have great difficulty controlling noise - the camera temp was ranging between 27- 31'c even though ambient was 6'c to 3'c.
It is cropped as I have still some collimation issues to address.
Thanks for looking.
Graham
