I have struggled and struggled to get a decent image of Helix.

Three nights over three seperate months I tried to get a usuable stack but failed miserably. The stacks were way too noisy and the detail grainy. I thought that maybe it was impossible from my Bortle 7 backyard.

After watching a video on WBPP multinight stacking technique, I thought I would try it on this object. It was a perfect choice as the rotation over multiple sessions did not matter due to the object being central. I figured I could cropped out the rotational artifacts post-processing.

So more out of getting a better handle on Pixinsight and WBPP, I stacked all three night together with their relevant darks and flats as they had different exposure times and gains.

The result is not too bad. Still alot to learn but overall happy with the result.
