M101 - An attempt at RGBHa

[mightymonoped]

First time trying to use the Pixelmath/SPCC approach to merging RGB and Ha data.

In this case only an hours worth of Ha so I've been a bit cautious on pushing the saturation.

Not as good as some of the versions on here but this is the first time I have felt happy with the process as something controllable and repeatable.

Pity I never had good flats for this set of data but I'm definitely going to add more Ha to it, now that I know how to add it to the whole.

Stacked and registered in AstroPixel Processor for both RGB and Ha images (both treated for Light Pollution too).

NoiseX and BlurX for the RGB in PI

SPCC for RGB image

Pixelmath Ha merge (at $T* 0.3 + Ha* 0.7)

SPCC again

Super Hyperbolic Stretch using Bill Blanshan script.

Saved as Tiff then artificial flattening using Astro Flat Pro in Photoshop CC.

Final saturation and Sharpening using APF-R (at 50% transparency).
