I was Lucky yesterday to Catch this loop prominence, which didn’t last long and faded away quickly.

It was very faint, so I had to push the gain quite high to make it visible. Here a color camera really shows it’s downsides. This ofcourse causes negative effects, as can be seen in the original stacked only frame here.

This morning, I decided to reprocess the original stacked only frame again. I applied an inverted filter, did some careful stretching and played around with the color channel sliders in BW mode to reduce the high gain effects to a minimum and was so able to squeeze out much more detail than I thought I could.

This is the final image from yesterday’s loop prominence in the AR2303 / 2309 region.
