I imaged M81 and M82 last night using the Dwarf3. 400 subs using the astro filter followed by 200 subs using the duoband filter. I then stacked and processed both images. Following star removal, I then used the continuum subtraction utility on the red channel of the duoband image and combined it with the RGB image using the NBRGB combination script. This process shows the hydrogen areas of M81 quite well.
Some cropping was needed as, even though I roughly polar aligned the Dwarf3, the narrowband capture was slightly rotated. Star align fixed this well.
