Thanks Guys. The narrow band exercise was something diferent. It is quite a bit of work to finally get the registration right but thankfully Registar being one step ahead of most other registration programs managed it quite well. My initial attempt in IP3 was a real failure with the program having all sorts of problems and still didn't get it right.

Yes Daniel the colour is something diferent but it is growing on me. Just like green slime. I must try some other colour combinations and see if they are a little more paletable.

It is quite a drawn out process with the OSC ( Not a lot diferent from the RGB with a mono camera.), here is a bit of a simplified version.

1. Image Capture Ha, OIII, SII over several nights.
2. small DDP stretch on all raw images.
3. Register and align each group of images.
4. Combine each separate group of images.
5. Change combined images mode to Grey scale. (Very little colour from other colours was present so not worth worrying about separating into RGB first.
6. Re stretch these final grey images to a near final level.
7. Register and align the final greyscale images.
8. Combine and colour the 3 images.(I used IP for this while mapping SII=Red, Ha= Green, OIII= blue)
9. Take combined image into photoshop for a play.
10. Hopefully a half decent image to show for it.

An interesting test but next time I might use the bigger scope if I ever get the flattener for it.

Thanks for looking and commenting.
