Subject: Odd problem when using sharpening before stacking

Finally the sky was cooperative so I could image Saturn.

Before I started imaging I installed the latest 4.003 Version.

Strangely I needed to reinstall the Bayer codec before it would record

a movie. Seems like the old version does not work with the IIDC

version 4.003?

However finally I got around this small problem.

Today when I tried to stack the movies I ran into a strange problem

that  resulted in "false" colour images after stackting.

After experimenting with the settings I found that the option

"Sharpening before stacking" was the reason for the strange results.

It seems to happen only at the setting "Medium-High", lower settings

seem to be OK. 

I used the same setting on the older versions without problems.

I uploaded an example showing the problem:
