Hi, I am hoping someone can share their workflow in the RBG combine tool with latest version 1.079. I have some Ha and Oiii data, noticed that in 1.079 I can add the channel with a HOO 1 or 2 formula but not having much luck to tease out the colors.

Hi Tim Looi

Please, check out the video of B&K Science and Astronomy on You Tube.  Here is the link :


I processed my Duo-Narrowband data of the Rosette Nebula following his workflow with Astro Pixel Processor. The result was great.

It's done with an older version of APP, but I don't think that the RGB combine tool has changed that much. 

Also the videos of Rutger Bus and Astrostace gave me that extra information that I needed concerning Duoband processing with APP.

Here the link to Rutger Bus' video:

Here the link to the video of Astrostace: 


Good luck!
