Trunk Nebula in IC1396
Hubble pallette,
LRGB
R as SII+.1Ha
G as Ha
B as OIII+ .1Ha
Ha 1200 seconds (4)
OIII and SII 1500 seconds (7)
SBIG ST2K
TeleVue Genesis 100mm @f/5
Pixinsight
Used the Ha to "juice up" the other two channels...and I am not sure it was the best call.
It allows more flexibility in adjusting R and B where signal is weak.
On the other hand high signal areas (around the trunk) become "blown out" and are seen as white.
