Not much can be said or read about Sh2-124 molecular hydrogen cloud in the north-east Cygnus frontiers. It is pretty large but not too bright. The whole area is filled with the hydrogen, so every place you look you can see red. Not much science work has been done there, it is even not certain which stars are responsible for exciting hydrogen to shine in red. Pretty mysterious nebulosity.
