Helix quad narrowband teaser
Hi all,
Today I started tidying up about 190 hours worth of Helix data and created 4 drizzled narrowband masters. SII, as expected, is very weak in spite of a significant integration - if anything, SII may be useful for making star masks.
Adding other channels to Ha enhances SNR in the brighter regions, but the outer bows weaken, so I may use straight Ha for Luminance.
NII, OIII will be used for colour, and will see if SII will be useful. I may also try blending Ha and NII into one colour channel, possibly red.
