Help adding Ha and OII to RGB with different focal lengths

@luckybudd Hi!

You want to process the RGB and IDAS images separately because for the IDAS images you want to select Ha-OIII extract Ha and then Ha-OIII extract OIII.

Once you have the integrated RGB image (combining both focal lengths) and the separate Ha and OIII images, you can load all three as lights (no calibration files), go to tab 5 and normalize them. This will also register the images to each other. Then save the registered images.

The resulting registered images can then be loaded in the Combine RGB tool to create the RGBHOO image. 

HTH, Wouter

Brilliant!  Thank you!

So, if I understand correctly: 

1. Integrate the RGB files.  Set aside the stacked RGB file.

2. Reopen APP and load the IDAS data, creating both an extracted HA and OIII file.

3. Reopen APP and load ONLY the completed 3 files as LIGHTS (the RGB, HA and OIII) and normalize them (don't integrate).  Are there any special settings I need to do at this point, or leave everything as default?  Then save the new register images (is this in tab 4?)

4. go to combine tool and select RGBHOO like normal.

Thank you Wouter!  Very helpful!

@luckybudd That's correct but no need to restart APP. In tab 1 you can clear all loaded files and then load the ones you want to integrate. 

Ahhh!  Merci!!
