Tarantula Nebula in Hydrogen Alpha

Howdy
After getting home from the cinema the moon was already up so after doing some drift aligning to recheck polar alignment I shot the Tarantula Nebula with the Baader 7 Nm Hydrogen Alpha filter. 10 inch f5.6 newtonian modded 350D camera, IEO 400 2x20 minutes hand guided, moon well up at the time. 1 dark, 1 flat and 1 offset processed in IRIS, Blue and green channels discarded, then masked and finished in Photoshop and Noiseware. Still a bit noisy, would be better if I did another 2 or 3 exposures but was enough hand guiding as it was lol.
