Hi All,
I'm having a dilly of a time removing these gradient circles from my composite image.
This is from my Canon 700D (T5i) DSLR on a SolarQuest tracking mount.
The photo is a composite of tracked 1/1000s, 1/500s, 1/250s, 1/125s, 1/30s, 1/8s, 1/2s
ISO 100
The moon is from a 2second exposure (I'm still working on it).
I took these in Onyx, Arkansas over about a 3-minute period. Clear, blue skies.
The problem with Photoshop stacking is that it brings in all the halos from each exposure.
I'd like to be able to remove the gradient without sacrificing corona streamer detail.
I've tried a number of different ways in Photoshop and Pixinsight with no luck.
Any thoughts or suggestions? I don't mind re-stacking if I need to modify each exposure to remove it.
Thanks.
