LBN 239 and 243 in visual spectrum


Two of my latest photos are overlapping, so I was able to stitch them together to this two panel mosaic image.  This time in visual colors combined from narrowband channels, H-alpha, S-II and O-III. Mapped color version can be seen in my previous post HERE

LBN 239 and 243 in Constellation Cygnus
Please, click for a large image

Image is in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulphur, G=Oxygen and B=Oxygen + 10% Hydrogen to compensate the missing H-beta emission.


Image info and the technical data
