I decided to have a go at this data as I really like the 'Pacman'. I used, out of the data provided, 318 subs each at 1 minute long exposure time. This totals to an integration time of 5 hours and 18 minutes. I had to crop it a fair bit, hence the dimensions are a bit unusual, but there are so many stars! Pier 5 uses a Takahashi Epsilon 180 F/2,8 astrograph, on a Skywatcher EQ 8 mount with a ZWO ASI071 Pro Colour CMOS camera.
Thanks everyone and have a good night...
