Synthesizing green channel
I used an optolong enhance filter on my 183mc, split the Ha and Oiii channels using the debayer algorithms. My question is can I take these two channel s and synthesize a green channel to do some Hubble pallet work?
I have options for that in PS, but I would have to convert them from fits to maybe a tiff to use that. I heard PI has an option for it but couldn't figure it out in APP.
I guess maybe a better question is how to do a SHO image when you only have Ha and Oiii.
I have some data here (in the drive link) if anyone wants to play with it. It is made up of 3 minute images with a 183mc pro and Lenhance filter. I took the images and split the channels in the debayer settings. So far this is the best I have managed and I fumbled around arriving at this result.
So with just Ha and OIII I'm not 100% sure, but your colors you ended up with look similar to where Mabula started out with in this tutorial. It already skips to the part where he goes about changing the colors, hope that helps! (basically with/without star color calibration you get the biggest difference as a starting point for it, and ofcourse how you assign the colors). For more aggressive changes I think the other packages are still in an advantage tool-wise.
