I was using an 80mm refractor at f/6.3, a Vixen Atlux mount, PHD autoguiding and an Atil 383L CCD camera with a set of Astronomik narrowband filters.
The total exposure times were 40 min using an OIII filter, 40 min using an SII filter and 4 hours using a H-alpha filter.
Ten min sub-frames were captured with matching dark-frames and combined with Flat-fields to reduce the effect of vignetting in the final image.
