Details:
On the evening after passing through Earth's orbital plane the comet's anti-tail was captured on camera. While clear all day, clouds moving in just before sunset were sufficient to kill plans to use a star tracker to get closeups of Comet 13P/Olbers and globular cluster M5 alongside A3. It was first detected at about mid-twilight on-camera and in 7x35 binoculars but noticeably fainter than 2 nights ago. Tonight the nearly Full Moon kept the sky bright and the landscape lit, so perhaps that's why I failed yet again to see it naked-eye.
