We've been following 3I/ATLAS from @cefca-oaj.bsky.social in Spain (Teruel)!
This is just the 3rd interstellar object that we see enter the Solar System.
I created this video with the observations🔭 we have made: you can see the comet moving through the field of stars.
We hope to get more data!

We used the JAST80 from @cefca-oaj.bsky.social in Teruel (Spain), with a large field of view, to observe less ionized oxygen ([OII], white contours).
We see it separated from [O III], in layers. These structures are too small to be resolved in distant nebula, but easy to see in Milky Way objects. 🔭

Correct background subtraction is very challenging but crucially important to study structures with low surface brightness. Great work by colleagues at @cefca-oaj.bsky.social and other institutions! Can't wait until we're ready to apply these techniques on our big surveys, too…
Amateur-level hardware can do science! A new paper by David Martínez-Delgado et al. shows a decade of results from an amateur/professional survey. 🧪☄️ #astrophotography
The pic on the left is from DESI, the right from their survey; notice how there are no horizontal/vertical mosaicing artifacts.
