Description

This color image follows the one H-Alpha previously published:

http://astrob.in/320978/B/

Sh2-54 is the broad nebulosity covering the whole image.

NGC 6604 is the open cluster.

The small bright nebula is Gum-85. The ring around it is Gum-84. The "Nested Egg" nebula is Gum-85 and Gum-84.

If I had known that this region was so interesting, stellar objects and alpha Hydrogen, I would have taken it earlier, because in October the constellation starts to be a bit low for me, and I would have spent much more time to add more frames. Now it will be for the next season.
