My first try on combining LRGB data with H-alpha. All data was taken during two following nights. The luminance and halpha data are ok. I need more RGB data because its pretty noisy. I used all kind of software noise reuction algorithms (randomly :D). Finally it looks better than i expected it from the RGB data.

L: 40 x 300s 1x1 binning
R,G,B: each 6x 300s 2x2 binning
H-alpha: 8x600s 1x1 binning
