Deep sky target that has been on my imaging list for years.

Never got round to it with so many good imaging targets near by.

Poor British summer weather this month so could only collect 6 hours of data.

Just enough for a nice bicolour narrowband image.

Data collected on three nights. 4th, 24th & 25th July 2017.

ha/oiii/oiii image with 5 hours 40 mins of data. 9 x 20min Ha 1×1 binning, 8 x 20min Oiii 2×2 binning.
