Description

A HOO version of the Lobster Nebula. Some issue with the O3 caused the unusual crop and the dominant red colour but I felt it was a reasonably balanced arrangement of parts.

B

Messing around with color :-)

C

More as it came from PI, with more variety of color and more of the slightly errant O3

D

Letting the O3 through more

F

A little sharper, small adjustment, slightly less saturated

G

A bit brighter and a bit less saturated. Not necessarily a better version but perhaps some more obvious detail in the top left area.
