I spent a total of four nights on this target, two without a filter and two with a duo narrowband filter. This galaxy has one of the largest known Ha regions which is the reason for using the narrowband filter for a couple nights, it boosts the Ha signal significantly. I used a script in Pixinsight to combine the two images.
