I'd like to say I know what I'm doing but I cheat and let the camera do all the work.
It's a Olympus OMD M5 with a 40-150mm lense and 1.4x teleconverter. The camera has a pre set Sunsets setting I just used that.
Yes there was smoke haze that night (sky was red) from the Adelaide Hills fires.
I've been messing with the manual settings but that is still a work in progress.
