Description

The final image after a long and strenuous process of acquisition and especially processing, I managed to finish the Elephant Trunk. I was hoping for 4h per filter, but I had to stop due to the weather at 10,25h. Almost missed the entire S2 and O3 series due to catastrophic flats... The processing was hard in order to get the colors right and it only worked when I combined the channels in non-linear. I had some moments when I thought that I had to start all over again, but finally it came out close to what I intended. I hope you like it.
