Hi! I would recommend that you don't use CLAHE images for stacking, but rather use the "disk" ones, _then_ do contrast enhancement like CLAHE or something. You could even use the batch mode for this, with a script. That is to say, use the "batch mode", then select custom process and use this image math script:
```
#
# Performs stacking of several images processed in batch mode
#
[params]
# banding correction width and iterations
bandingWidth=25
bandingIterations=3
# autocrop factor
cropFactor=1.1
# contrast adjustment
gamma=1.2
# doppler shift
doppler_shift=3
[tmp]
corrected = fix_banding(img(0);bandingWidth;bandingIterations)
bluewing = fix_banding(img(-doppler_shift);bandingWidth;bandingIterations)
redwing = fix_banding(img(doppler_shift);bandingWidth;bandingIterations)
[outputs]
decon=rl_decon(corrected)
blue=rl_decon(bluewing)
red=rl_decon(redwing)
[[batch]]
stacked=stack(decon)
stacked_blue=stack(blue)
stacked_red=stack(red)
[outputs]
stretch=auto_contrast(stacked;gamma)
details=draw_obs_details(draw_solar_params(stretch))
colorized=colorize(asinh_stretch(stretch;500;5);"H-alpha")
doppler=linear_stretch(saturate(rgb(stacked_red;(stacked_red+stacked_blue)/2;stacked_blue);1.1))
doppler_protus=linear_stretch(disk_fill(doppler))
```
You should get much better results.

Thanks, I will try it next time
