There are many examples where we image an object that is predominantly a full continuum
spectrum object, a galaxy or a reflection nebula for example, but it also contains emission
line nebulae components. Capturing both a full spectrum RGB image and narrowband
emission image which are then combined may reveal more information about the object
and create a more interesting and complete image.

With so many new advances in Pixinsight processing methods, one of your members Dean Ashton has put together a PDF describing his current workflow for this technique and is available for you download below.
