Jeroen Moonen just made a very nice multi-channel H-alpha OIII mosaic:

This is a stunning Veil Nebula Jeroen 😉 ! Very nice...

How did you register the different narrowband channels ? Did you register them all at once as a multi-layer mosaic?

His answer:
 
Hi Mabula, I loaded all of the calibrated frames (2x Ha + 2x O3 stack) into APP, did a star analysis on all four stacks and after that I

registered them (I let APP decide which frame it wanted to use as a reference). After registration I deselected both O3-stacks in the file list

and did an integration, obtaining the complete Ha- mosaic. After that I deselected the Ha stacks and selected the O3 stack and did a new

intergration for the complete O3 mosaic. During the entire process I used the settings from Sara Wagners video on your website.

 

Excellent Jeroen,

that is actually the best way (technically speaking) to register a multi-channel mosaic. Register all panels of all layers simultaneously 😉

I'll make a workflow topic for multichannel mosaic and direct it to this topic 😉

Cheers,
