That's the way Doug. Go deep mate. Shoot some 20 or 30 min subs if you can. I think I've mentioned this before, but the S/N ratio of a CCD image increases linearly with the square root of the exposure time. This means that quadrupling the exposure time doubles the S/N ratio. So take the longest effective exposure you can. Look forward to seeing the final rendition.
