Sh2-122
in Pegasus - LRGB

I don't know what to call this one. A Dark Nebula? It is a cloud of gas
being illuminated by the bright star Markab in Pegasus. There is no
narrowband contribution from this gas cloud. Colour is muted but one
needs a LOT of luminance data to tease out any structure. It is FAINT.
There are a TON of faint galaxies in the background if you want a
challenge!
