Looking at the picture, we see how the ion tail of 3I/ATLAS is clearly showing better and better, thanks to the improving perspective. We could see it spanning at least 0.7 degrees, in the NE direction. It is also well visible the anti-tail, pointing to ESE.

The image above comes from the sigma-clipping combination of 18, 120-second exposures, remotely taken with the [ARTEC250+Paramount ME+C3Pro61000EC](https://www.virtualtelescope.eu/the-artec-10%e2%80%b3-f-4-5-250-1125-mm-astrograph-paramount-me-moravian-c3-pro-61000ec/) robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy. The comet was 14 deg. above the easter horizon, with a bright (phase: 61%) Moon at about 70 degrees from it.
