Dancing in the Dragon's Jaws - Lum Ha RGB
NGC 6188 is an emission nebula located about 4000 light years away in the constellation Ara. This area is commonly known as the dancing dragons. It is a starforming nebula filled with young stars, some of which are only a few million years old. They were most likely formed when the last batch of stars went supernova in that area.
The data for this image was captured on two nights - 21 June 2015 and 19 July 2015. This is my first serious attempt at mixing luminance and Ha data, and blending it with a traditional RGB data set. The processing turned out to be a little interesting than I initially thought. The Ha data with its strong signal can both flatten and drastically alter the underlying colour data.
My favourite part of the image is found in the lower left portion where the blue reflection nebula is located. I really like how it is mixed with the subtle pinks hues.
