Since the weather up here has been less than supportive for astronomical imaging for a long time, I have played with an older data.
Heart & Soul Nebulae
IC1805 & IC1848
Image is in HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
My photos, from several years, are used to combine this panoramic image of IC 1805 & 1848.
This emission nebula area is located in constellation Cassiopeia at distance of about 7500 light years.
I have made a scale study to show the apparent scale in the sky, it can be seen here:
Image is in visual spectrum, mixed from the same narrowband material, than image above.
