Well, I am pleased to have a go at this data, as I really like M78. I used 79, 4 minute long exposures, which equals 4 hours and 15 minutes integration time. I had to crop a fair bit out, due to the gradient being too hard for me to manage, but I just about got there. A few of the stars went a bit awry during processing, but I liked the rest of it, so decided to sacrifice those for the greater 'good.' Have a great week everyone.
