Really lovely Gina, you should post up the Ha only as well, it seems to shows the thin tendrils of nebulosity better in Mono and it's not often I say that.

Wonderful images! How did you managed the stars?

Thank you.  Astrodon 3nm filters and avoiding saturating the stars by keeping the gain/exposure combination low enough.

Hi Gina, Lovely to see you "getting your mojo back" and  imaging again. I love both images the rich red and the wonderful Ha image and both well processed too.
