Reprocess NGC 3372 Carina Outer Regions

[Startrek]

Since I’m isolating with a 2nd round of COVID ( yes it is still active in our communities) so decided to re process my Carina image which did provide a subtle improvement. Star color is more uniform with red / blue outer halos now reduced / removed on small to medium size stars. SV Decon did work better this time than Synthetic mode. Improved contrast and brightness.

Sharpen default
SV Decon sampled ( 8 samples ) iterations 12 , increased de ringing parameters to soften coalesced stars in white nebulous areas ( sort of worked ok )
