PHD autoguiding was used with an Atik 383L mono CCD camera and a set of Astronomik narrowband filters.
The total exposure times were 60 min using an OIII filter, 60 min using a SII filter and 3 hours using a H-alpha filter.
ten minute sub-frames with matching dark frames were captured and they were combined with flat-fields to reduce the effects of vignetting in the final image.
