Different NB Combinations

Post by h2opolo » Thu Apr 20, 2017 7:17 pm

When you want to create an image like HOS or SHO or some other varied combination is that done in processing or is that done when imaging?

I'm thinking you would assign the filter to one of the RGB categories in processing. So for this one Ha would be in (Red), OIII would be in (Green) and SII would be in (Blue). Is that right?

It does not seem you would do this in data capture.

Or is stacking where you do it?

Yep, typically taking the Hubble Pallet

Red = SII
Green = Ha
Blue = O3

Of course trying different combos will produce different results. One thing I've always found is mapping Green to Ha always overpowers the image with Green. Then you need to do a selective color trick to tease our browns, golds, yellows, and blues.
