Description

This was my parking target while I was waiting for Rosette-Cone region to clear the horizon. 

I had to ditch almost 50% of Ha subs due to clouds and bad stars, I think there were gusts during imaging. But still the Ha signal is overpowering on what was stacked and O3 is almost non-existent. 

I tried a few mixes and like a creature of habit, went back to the SHO mix. My initial version was blown out and Anis reminded me to check the S2 stack as it had a lot of structure, so went back and redid the SHO version slowly. 

Looking at the processing history in PixInsight, I see SCNR as the most used process, way too much green and the initial SHO blend looked like a banana 

Hope you like this result. Clear skies!
