Help
My just posted try at Lovejoy has a glaringly obvious artefact in the centre of the comet. This artefact is obvious in the DSS autosave image.
Thinking that this must be a problem with DSS I have done another stack
of 15 subs from the original 24. If you increase screen mag to 175% you
can see the shape and shading of the artefact amidst the glare of the core. Is this genuine, or a stacking/ processing problem? I have done
almost nothing to the image other than a bit of saturation. No contrast
or sharpening adjustments, just resized for posting.
Any ideas anyone?
