I believe this has something to do with Normalization. I can stack the individual sub-frames separately successfully, and the O3 and S2 channels mosaic stack normally. But regardless of what I try in settings the Ha channel will not stack properly. This image is with LNC disabled. The top frame seems to work normally, but the bottom does not. With LNC activated both frames are almost fully washed out as is the bottom frame of this one.
I've stacked many dozens of images and several mosaics and have never seen this before.
Any suggestions as to what is going on here?
Thanks,

That's a new one, can you see a normal signal when that lower panel is stacked on its own?
Yes, I can stack each of these HA frames individually and they look normal. It is only when I try to run it as a mosaic does this happen. When I have time I'm going to stack the top and bottom 3 channels separately then attempt to register, normalize and integrate them as two separate images. Can that work?
You should be able to load them all in (each panel separately), register and integrate all those as multiple channels. Then combine them into what you want for panel 1 (rgb combine). Do the same for the bottom and then load those integrated panels as new lights and make a mosaic... that might be interesting to try.
The separate integrations of each mosaic section and then integrating them as a second step worked famously! I hope that this was just some weird event as a result of settings or the data since it took a bit more time, but in any case the results are spectacular! Thanks for the help.
I can't upload images to the forum right now, but here is the link to my Astrobin.
Superb! Yeah it is still a bit weird and I don't think that should happen, so could be some weird step somewhere. There are however more ways to Rome. Very nice result!
