Star alignment prior to LRGB combination
« on: 2012 September 01 17:59:42 »
Hi,
I am sure there is an obvious answer to this but I am having huge amounts of trouble aligning a stretched RGB image with a stretched luminance image.

My L image is 1x1, the RGB is binned 2x2.  As I understand it, the star alignment tool handles scaling appropriately. So prior to LRGB combination, I tried star alignment. After numerous iterations it failed.
I've tried this with several images and it fails each time.

How do I get this to work? It appears that I am running the latest version of PI 1.07.06.0793 since no updates are available to me.

If needed I can post the files.

Use the Dynamic Align tool.

Is this my new friend Ram from AIC? Anyway, you can upsample individual 2x2s to a single reference 1x1 during preprocessing in either BPP or separate modules. By using DynamicCrop, you can keep the Chrominance and Luminance Masters precisely registered when trimming off their respective problem borders. I do that before DBE/BN/CC as we don't want the black borders and artfacts used in the calculations. Good to see you Steve. Thanks for the DynamicAlignment trick as well!
Best always, Warren
