The consequences of letting Hydrogen alpha dominate the image construction

I like to think that these are two of my best narrow band images yet. The raw data were recorded using a Televue NP127is scope @ f/4.2, Astronomik 12 nm filters, and a QSI683wsg camera.

I used the following color palette when building the two images:

Luminance = H alpha, Red=H alpha, Green= H alpha, Blue=OIII

For most nebulas, far more information content is recorded using an H alpha filter than an OIII filter. Hence I chose to let the H alpha channel dominate the image construction.

I also posted these images to the QSI group. There is no need to look if you have already seen them.
