Hello,
there are debayer modes for DuoNarrowband filters in APP. My question is, how do they extract the Ha and OIII information? Is it a splitting of the RGB color channels or is it a "real" CFA split? If it would such, the resolution has to be 1/4 of the original image (but its not), so i assume its an RGB seperation?
Couldn´t find any information about it.
Cheers Frank
This is easily done in tab 0. There you have the bayer algorithm that you can change to "Ha extract" for instance or any of the other options. Set it to your liking, then go and load in the lights. Process the Ha, and then clear the data, change the algorithm to OIII (for instance) and load again. It's not a simple channel-split, but a bit more intelligent.
Hi Vincent,
yes i know this, but i wanted to know whats happening behind the scenes. I assume its splitted in to its 4 pixel values (RGGB) and resampled again?!
Know what i mean?
Cheers
Frank
Ah yes, so I have no good knowledge of what the algorithm is doing internally. It's likely something of a resampling like you mention, but it also retains resolution by doing so etc.
He's very busy indeed trying to speed up the next release. 🙂
