R=6x5min, G=6x5min, B=6x5min, Ha=10x5min @ -20 degrees C

Processing Details:

Individual colour channels had basic processing in 'CCDSoft', Dark subtract, flat field and Bias processing, then 'added'. The final file for each colour channel was then transferred to 'Photoshop CS3' for combining, and using levels and curves to bring out colour balance and the outer nebulosity. Noise reduction on some of the colour channels was also processed in Photoshop.
