On 2025-10-02 I observed interstellar comet 3I/ATLAS (before passing Mars) at remote 0.25-m f/3.8 reflector T75 iTelescope.Net, Chile. 1st photo is in color.
I also observed it on September 27th - Autumn Astronomy Day.

I have an interstellar comet in view! This is almost directly over the City of Boston so the light pollution does not help but it's in the center and looks pretty cool.
Wonder if astrometry can identify it @kat-astro-bot.bsky.social

I measured the magnitude of the interstellar comet 3I/ATLAS from my photos (July 17th - October 2nd) using Tycho Tracker v.12.6 software. I used the ATLAS catalog and 10000 km aperture radius.
