This is my version of the Rosette nebula in Narrowband.

I only have about 3 hours a night to shoot this target so it felt like it took forever to gather the data. I fell like it needs more time in both SII and OIII, but at the end of the day I'm happy with the results.

As always any C&C are most welcome. Thanks for looking
