Angerman 🦅Hobby update! 🔭🛸👾Last week some clear nights; and with my second set I didn’t knew what to target and shoot. So kinda was hopping around and found this very very very faint target. Didn’t knew what it was; had to look it up. Ultimately I had to do 600 second and 1200 second 🫣 subs. Yeah. That’s 20 minutes for one shot. And that a challenge I didn’t tackle before.But.

carstenraddatzIf you too want to know when the long awaited recurrent <a href="https://mastodon.social/tags/supernova" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#supernova</a> explosion of T Coronae Borealis happens, well just wait. You didn't miss it, it hasn't happened yet, however pre-eruption started.Last outbreaks were May 1866 and February 1946, so 2025 is likely. T CrB has two components: a red giant star in close orbit with a white dwarf. Theoretically accumulated mattercould push past the 1.4 solar mass Chandrasekhar Limit, forcing a Type Ia supernova.
