Hi everyone !
Here are two pictures from the Dzeta star area in the Scorpius constellation.
There is an HaLRGB version in "normal" colors and a SHO version, in narrowband filters. This one is perfect to see planetary nebulae
By the way, we've added some notes on this last one to show you some planetary nebulae and specially two of them we've discovered with Matthias Kronberger: DeGaPeKn1 et DeGaPeKn2

Here is the picture:
