Sometimes More is less!
The Soap Bubble nebula (PN G75.5+1.7) from 1 hour of narrowband data (Ha and O3). 5 minute exposures (30 minutes through each filter) captured by AstroDMx Capture through a William Optics 81mm APO refractor with a QHY Minicam 8 camera/filter wheel. Processed in PI, SASPro and GIMP3. Rendered as HOO. 'RGB' stars were constructed in Siril from narrowband data using the Standard Continuum Mapping pixelmath procedure.
If we include the 30 minute worth S2 data in a SHO/NBN palette (giving 1.5 hours total exposure), the Soap Bubble is much less pronounced. This is because most of the information on the Soap Bubble is in the Ha and O3 channels. A blend of HOO and SHO gives a reasonable compromise, with the Soap Bubble being visible along with some of the hues associated with the SHO.
