DMK with Astronomik RGB filters. Green filter yielded the brightest image by far. From 1500 frames only the best 30 or so were kept from each colour channel for stacking in Registax 6. Linked wavelets used to process each image which were then aligned and combine in Photoshop CS6. Here a 15% opacity mask was used over the green image to avoid the final result looking too green. A soft light high pass filter applied to the final image.
