The Iris nebula is a reflection nebula in Cepheus that is lit by a 7th magnitude star at its centre. This is my first series attempt to photograph it and despite some guiding issues which only allowed for 5 good frames during the night, I was quite pleased with the result. 5×150 sec subs with 25 flats, 25 bias, 10 dark frames.
