Had a go at removing the stars in this version of IC 2944 in PixInsight using MMT and star masks. Lots of control of the process but then lots of umming and ahhing... I usually remove stars in quite a rough way as I add them back in later but for this I tried to maintain some detail.
Still a HOO image. Have some SII and RGB but yet to add this to the mix.
