The Propeller nebula

Image Description and Details : The Propeller nebula is a target that I have tried before in 2019, but this time I wanted to add more Oiii and make it stand out in the final image.
The data captured this year wasn't really enough, so I stacked the new data with everything I had from my previous attempt and I can finally say that I am pleased with the final result.
