Hello all,
Advice needed...
Recently noticed some weird things after using my new 400mm f5.6L lens.
Stacked/Combined images seem to have some strange 'wiggly worm' artefact throughout the image - it's not present on ANY of the individual subs either...checked them all.
Below images...
Left: Stacked/Combined using Adaptive Add (problem obvious when stacked using Average too)
Artefacts circled!
Right: same data combined using Sigma Average
Stacked in Images Plus.
Any ideas as to what's going on?
Doug
