Weird lines in my integrated channels
I shot with Ha-OIII filter on a DSLR and got these weird lines. These are in both my HA and OIII channels. I am shooting with A7RII and a 600mm lens. I can load all my data (About 112 50s frames and equal number of darks) if needed
It happens to me too, but with smaller and shorter lines and "spaghetti" stripes, but i think the reason is the same...
I'm waiting an answer too....
I even tried with force Bayer CFA and still have the issue.
Did you use the Ha-OIII algorithm?
Yes, on the first screen I Did HaOIII extract Ha and then HaOIII extract OIII. I used the same steps you outlined in my earlier question few months back.
Mm, it looks like what is called walking noise (though it looks quite strong here so not 100% sure), which is fixed by using dithering. Do you dither?
@vincent-mod will longer exposures and higher ISO help here if I cannot use dithering
Maybe longer exposures, but I'm not sure. If it indeed is walking noise, dithering would be the only solution I know of (I always dither so never looked more closely into it). APP, or any other program for that matter, will have problems with this.
