No, only the r_lights are necessary I think. Will upload them tomorrow on Dropbox or similar.
I made another stack of Orion with over 500 lights, even greater negative values are the result xd
Exif: 1.6sec exposure, iso800, f4.5 sigma 70-300mm
Visually the result seems fine, I can see good details of Orion taking into account that no tracker was used and exposures are very short.
We have 201 parallel blocks of size 59 (+59) for stacking.
19:18:32: Starting stacking…
20:38:16: Pixel rejection in channel #0: -6.578% - -737.116%
20:38:16: Pixel rejection in channel #1: -5.298% - -615.811%
20:38:16: Pixel rejection in channel #2: -7.791% - -689.547%
20:38:17: Rejection stacking complete. 524 images have been stacked.
20:38:18: Integration of 524 images:
20:38:18: Pixel combination … average
20:38:18: Normalization … additive + scaling
20:38:18: Pixel rejection … linear fit clipping
20:38:18: Rejection parameters … low=5.000 high=5.000
20:38:21: Background noise value (channel: #0): 0.101 (1.535e-06)
20:38:21: Background noise value (channel: #1): 0.084 (1.288e-06)
20:38:21: Background noise value (channel: #2): 0.088 (1.341e-06)
