Common 22 halo


37 hdr frames stack. Here's the same image with Photoshop usm filter to boost the contrast.
Here checking the 46° halo and infralatereal arc. After some heavy usm'ing the first one shows up but just barely. 28 frames.
41 frames stack. I suspected 9° halo but the stack reveals no sign of it.
