The constraints on the orient were made to allow the large globule and stream of dust to be included in the image, but to remove the 10 the magnitude star at the NE corner of the field. We are not concerned with cosmetic effects that the proximity of this star may cause. We have decided not to include shorter exposures as a consistent S/N is more valuable than artifacts that can be later removed.
