just show my recap of my observing from September 7th, 2026 near Ashton Idaho (north of there) in SQM skies of 21.8 to 21.9. I show the Milky Way and my sketches and SeeStar Images from two nights (September 7th and September 9th, 2026 for the SeeStar).
To read and watch all the material head over to Eadsy Astronomy and please join our community there to get first notice and my indepth articles on my observing and other information there! LINK.
The unbarred spiral galaxy NGC 7331 in Pegasus—often referred to as "the Milky Way’s twin"—has offered observers a rare occurrence. Between July 2025 and September 2026, the galaxy hosted two consecutive Type Ia supernovae.
Let me share that this is significantly rare. Extragalactic supernovae typically erupt once per galaxy every few centuries, making back-to-back "supernova siblings" within ~14 months in a single target a fascinating cosmic coincidence.
