Best method to combine LRGB and Ha/OIII data

Bruce Donzanti

Hi Adam

I have collected a lot of broadband and narrowband data on M1.  Attached is the NB image as I collected those data first.  After I finish collecting all of the LRGB data, I will process it as the Crab in BB vs. NB looks so different.  However, I eventually want to combine all of the data.  I will rerun all of the raw data in WBPP but was thinking how best to blend in the NB data with the BB data.  In the past, I have used the NBRGB Combination script when adding Ha to an RGB image.  There is now the SetiAstro Continuum Subtraction Utility script.  So, I am not really sure what is the best approach to process and combine these data.  I quickly looked at the LRGB/RGB and NB videos, but please point me in the right direction as how best to accomplish this.

Thnk you,

At the moment the best videos that demonstrate the idea are these two:

and

I will likely post more videos on this subject in the future.

Let me add that I show how to use ImageBlend in many ways- quite a few examples in NB FastTrack.

ImageBlend is the key to doing the job of what you want in PixInsight.

Thanks- very helpful. I have used both ColorMapper and NBN a lot but only alone and in the most straightforward ways. These approaches open a lot more blending possibilities.
