The data for this images was collected on three evenings (02/03, 17/03 and 19/03/2017). North is up. My aim was to show the hydrogen gas being ejected from the galaxy, hence I used the CLS light pollution filter which suppresses the continuum of the stars a bit.
Technical data: 8" f/8 GSO RC and PrimaLuceLab 700Da cooled at -15 degree degree Celsius; ISO 3200.
The 23x5 min and 21x10 min exposures were stacked with DeepSkyStacker in auto adaptive weight averaging mode and further processed in Fitswork4, PS and Noiseware Community.
