Looking for some clarity on synthetic luminance generation
I'm having trouble wrapping my head around how it works exactly, and what cases it might not be ideal. I know from narrowband images sometimes it's better to use just Ha as luminance for a cleaner L layer as adding Oiii and Sii can make the L result noisier. But for LRGB images with equal weight RGB...

Re: I think my images are going well until I try to color them in the color module
Yes that one definitely needs Ha as luminance only. I put that one editing on hold too since I couldn't get it quite like Ivo's Not all is lost though I went to experiment editing some even older data I shot in ST and somehow ended up with at least one project I really like how it turned out. This d...

Re: I think my images are going well until I try to color them in the color module
You are definitely on the right track - if O-III is unusably noisy for whatever reason, then just use Ha for luminance but keep O-III for color (e.g. set green/blue total exposure to 0 in the Compose module). As always, all you need to do in the Color module, is to reduce red (or increase gren and/...

Re: I think my images are going well until I try to color them in the color module
^mike I do think I know what you’re describing and have noticed that in the past- it is from using luminosity masks with sharpening and denoise (you can see that on my rosette). I don’t like that so much which is a big plus for ST and I didn’t employ any of that in my hybrid one (ez denoise might do...

Re: I think my images are going well until I try to color them in the color module
I don't want to change course too much but your comments on methods made me try processing again in ST on an image I had issue with before and thought I just didn't have enough data It's about 2.5 hrs Ha and a little over 3 hrs Oiii. The oiii still seems pretty weak I first tried adding the oiii and...

Re: I think my images are going well until I try to color them in the color module
Non-linear stretching and then combining makes no sense... Is it likely you just stretched until you saw the detail "you liked" (which is mostly visible in the Ha) and then decided it was time to combine? That's what it is supposed to do and what its purpose is, but squashing and stretching the dyn...

Re: I think my images are going well until I try to color them in the color module
Thanks. If it appears Ha was only used as lum that was not intentional and I'm not so sure. They were stretched and combined, then total luminance extracted. Ha could have still been more dominant and that could have happened unintentionally (I don't really know what I'm doing or how pixinsight extr...

Re: I think my images are going well until I try to color them in the color module
^sorry I think that was between ivo’s comments and I missed it. No not that bad, but I don’t think anything i’ve seen yet from myself included out of ST that gets close enough to the look of those in terms of detail/contrast and overall look. My bastardized pix/ST workflow above seems closest to get...

Re: I think my images are going well until I try to color them in the color module
So I had started working on another version to try to do entirely in pixinsight to compare using an old workflow started no binning- crop then ez processing suite - decon on each channel, ez processing suite denoise on each channel. then combined to RGB, stretch all channels, extracted stretched lum...
