For this image Alun took 7x300sec sub frames in Ha and the same again in OIII, using Esprit 150ED Apo,314L and an SX filter wheel loaded with 2" Badder narrowband filters.  Subs were stacked in Astroart 5, moved to Maxim DL4 for colour combining (Ha,OIII,OIII) and final processing carried out in Photoshop CS2, adjusting hue and saturation to bring out the Hubble Palette.
