This is an animation showing captures in white light through a UV/IR Blocking filter and then through the same filter + an Astronomik UHC filter. The latter combo passes 2x40nm bands, one around H-beta and OIII in Blue/Green, the other band around H-alpha and SII in Red. Click "original" below right if you cannot see the animation. This is a very rich starfield in the plane of the Milky Way and the stars tend to overwhelm the nebulosity unless one processes the images in a strongly manipulative way, basically emphasising reds. The UHC filter makes the nebulae very prominent. While the North American Nebula and the Pelican become very prominent with their richness of Ha, it's worth noting that there are also benefits to the OIII rich (teal, blue-green) regions in the Cirrus Nebulae lower down in the image. Taken at a very dark site, Mag 21.6/sq arc-sec using the Kenko Skymemo mount, unguided.
