Calibration and stacking done with Images Plus. Background

applied then the stars were separated from the rest of the
image. This allowed different stretches to be
applied to the DSO and the stars. The star colour was enhanced. A

layer . Finally the star and DSO layers were
recombined to produce the final image. |
