Re: Flats strange display
Thank's
1) I know the visualization via. Status bar or context menu. But it can't show me the "right" picture, as right after a division with a copy image.

Re: Compare 16 vs. 32 Bit
Thank you for all your great tips & trick.
And to keep it 16 bit seems to me, the way to go from here.

Re: Extracting Ha OIii
Thanks Rudi
Yes R will be close to Ha.
But OIII is a mix of G & B
It will not work to add G+B.
I gees that's the reason it has to be done before Debayering so only part of GB are taken into account. I know its not the same as with monochrome camera. But the results look good

Re: different resolutions
Some times it helps to read the manual
I will try "coregister" but I gess it could be better to down scale by bin 2 first.
