[Sticky] Registration & Integration of a multi-channel mosaic - The Veil Nebula by Jeroen Moonen
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?
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.
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
